  • Sequoia Script Issues: Common Problems Discussed on MacRumors Forums

    I am posting this in the Sequoia forum because I suspect that the issue relates to security features in Sequoia. I have a new Mac Mini (M4) running Sequoia 15.5, and I have installed all the latest security updates. I am using an AppleScript in Script Editor that is designed to open the Terminal app and send three commands. However, the script executes successfully occasionally, while at other times it fails due to a keystrokes permission error.

    A standalone app created from this script encounters the same inconsistency. I have the latest version of Python3 installed on the Mini. The standalone app is crucial for me, as I want to set it as a login item so that it runs automatically in the event of a power failure and the Mac Mini reboots. The script used to work flawlessly on my previous Mac Mini (2014 Intel).

    Here’s a brief overview of the script:

    1. The script waits for 30 seconds to allow the Mini to fully reboot. 2. It opens the Terminal.

    3. It changes the command line to the “pigs” directory located in my user account. 4. It runs a Python script named pigs.py.

    5. Finally, it enters the administrator password via sudo. The main issue is the inconsistent execution. There seems to be no pattern to when it works or fails; it feels random.

    Previously, this script worked perfectly for about ten years on my older Mac Mini. I have reached out to Apple Support, spending around 40 minutes trying to troubleshoot, but they could not identify the problem. Given that the script occasionally runs without issues, this seems to indicate a potential OS issue. Any advice or suggestions would be highly appreciated.

    Thank you,

  • How to Check if an App is Loaded and Running on Mac

    If you’re trying to determine whether a specific app on your Mac is running, there are several ways you can do this. First, you can check the Dock.

    Running applications will typically appear there, often indicated by a small dot beneath their icons. Additionally, you can look at the menu bar at the top of the screen.

    Some apps will have icons there that indicate they are currently active. Another method is to use the Activity Monitor, which provides a comprehensive overview of all running processes.

    If you suspect that the app is running under a different user account, make sure to select “All Processes” under the “View” menu in Activity Monitor. If the app operates in the background without a user interface, it will still show up here, even if it doesn’t have a visible setting or GUI.

    You can also use the Command-Tab shortcut to cycle through your open applications. This will allow you to see a list of currently running apps, and you can use it to switch to any application that’s open.

    For some apps, they may not have a typical user interface or might close after executing a task. For example, if an app runs a command such as disabling Caps Lock delay and then terminates, it won’t show up in Activity Monitor or the Command-Tab feature.

    If you need to deactivate the Caps Lock delay without running an app, there’s a built-in command you can use in Terminal: `hidutil property –set ‘{“CapsLockDelayOverride”:0}’`. This command can be run manually after each restart or automated using a launch agent.

    To create a launch agent that runs this command automatically at startup, you’ll need to create a specific `plist` file in the LaunchAgents directory. This solution ensures that the command is executed each time you turn on your Mac, eliminating the need for manual intervention.

    By setting it up this way, you confirm that the command will be executed in the background without needing to visually monitor an app, as it operates silently without any user interface.

  • How to Connect Three Displays to a Base Mac Mini M4

    I’m looking for clarification on how to connect my current and future monitors to the Mac mini M4 that I have on the way. I’ve gone through several threads in the forum, but I still have some confusion, particularly regarding the terminology around USB-C, which I understand is more of a port type than a specific connection standard.

    Currently, I’m using an Intel MacBook Pro from 2020 with four ports. In my setup, I utilize the built-in display while having an external monitor connected through an HDMI port on a hub.

    Additionally, I have another monitor connected using a DisplayPort-to-USB-C cable. Since the Mac mini does not feature a built-in monitor, I plan to purchase a third external display to maintain my existing setup.

    From the tech specifications I’ve reviewed, I’m curious to know if it’s essential to select a monitor that specifically highlights Thunderbolt connectivity. Understanding the right cable types and monitor compatibility is crucial for ensuring that I can effectively replicate my setup.

    I appreciate any suggestions you might have regarding the necessary cable types or recommendations for specific monitors that would work well with the Mac mini M4. Thank you!

  • Is the M4 iMac with 32GB RAM a worthwhile upgrade or just unnecessary?

    I am considering purchasing the M4 iMac due to its capability to run the latest software and have a built-in screen. The configurations available for the iMac include the same 10-core CPU and 10-core GPU, with the primary options being the size of the SSD and the amount of RAM.

    Opting for the maximum 32GB RAM raises the price to about $2,000. I plan to use this machine largely for research, which involves having numerous tabs open simultaneously.

    I’m uncertain whether investing in 32GB RAM is a wise choice for a machine that some might consider less powerful. Alternatively, I am also considering the entry-level Mac Mini, which features the same CPU and GPU configuration.

    If both setups—maxed out with 32GB RAM—are theoretically similar in performance, I wonder if the Mac Mini would be a better choice for handling hundreds of tabs across multiple browsers. A concern I have is that the iMac, while equipped with a screen, may potentially underperform compared to the Mac Mini.

    Many people I’ve consulted highly recommend the Mac Mini, claiming it handles various tasks effectively, especially with the additional RAM. If the performance of the iMac is on par with the Mac Mini, I want to ensure that choosing the iMac doesn’t limit my experience or capabilities.

    In conclusion, I need to assess whether the iMac stands up performance-wise to the Mac Mini. It ultimately comes down to whether the additional features of the iMac are worth any potential sacrifices in performance.

  • Should You Buy the M4 Pro Now or Wait for M5?

    If you are considering the M4 Pro, one significant advantage is that it features Thunderbolt 5 ports—something that could be beneficial in the future, especially if you plan to use a dock like those offered by CalDigit. I recently acquired a used CalDigit TS3+ Thunderbolt 3 dock for $90 through Facebook Marketplace, and I’m optimistic that prices for future models like the TS5 or TS5+ will decrease as time goes on. There is a compelling reason to contemplate a refurbished M2-Pro or M3-Pro machine.

    Using a Mac that is 1-2 years behind the current model typically has minimal impact, especially if you intend to keep it for 10-14 years. However, I anticipate waiting until next year for upgrades. If a Tandem OLED display becomes available, it may be worth the wait.

    My current 2011 model is still functional, but it is becoming increasingly insufficient for my needs. As we approach spring, it’s essential to be mindful of the speed at which time passes. With that in mind, some may ask why not wait for M6 or M7 models.

    After all, someone currently using a 14-year-old machine can afford to be patient. However, the financial implications are significant; living in Eastern Europe, the price of a MacBook could cover four months’ rent or even a used vehicle. For those looking at refurbished options, it’s worth noting that M5 units won’t be available until next year.

    Given the age of the Intel machine in question, performance may not be a pressing concern. However, it’s vital to recognize that the M3 Pro is somewhat of an outlier in the Pro chip series, with lower performance core counts as compared to the M1, M2, and M4, alongside reduced memory bandwidth. If your work largely revolves around light tasks such as word processing, music, photo/video editing, internet browsing, and communications, the recent availability of the M4 in the refurb shop presents an attractive opportunity to upgrade.

  • M4 Pro 24GB vs. M4 32GB: Which Should You Choose?

    Hello everyone,

    I appreciate your assistance with my situation. I recently purchased a MacBook Pro M4 Pro (14-inch, 24GB) and have encountered significant memory pressure, hitting 83% with 4.9GB of swap usage while multitasking.

    This experience is quite different from my previous Intel MacBook Pro, where I never faced such swap issues. In terms of my usage, I typically have Safari (over 8.5GB), development tools (15.5GB), and various productivity applications open simultaneously.

    Although it’s possible to reduce memory usage by single-tasking, that essentially goes against the very reason I chose to upgrade. I usually only replace my MacBook every five years, so I want to make a prudent choice.

    My main dilemma is whether I should return my current model and opt for a refurbished 48GB M4 Pro instead, or if I should consider a refurbished base M4 with 32GB. The latter would provide more memory compared to my current 24GB, but with less CPU and GPU performance.

    Budget is a concern, as I do not have a lot of extra funds, yet I also do not want to regret sticking with the 24GB option if there’s a chance of finding a more suitable refurbished model later. I’m also curious if anyone has tips for managing memory pressure on a 24GB configuration, in case I decide to keep it.

    What would you do in my situation? Thank you for your insights!

  • Is upgrading to a patched 2015 MBP a smart choice for replacing our old 2015 model?

    stp479, a newbie on MacRumors, posted on January 9, 2025, expressing interest in purchasing a 2015 MacBook Pro (MBP) that has been patched to Sequoia. The poster is considering this option as a way to replace their worn-out 2015 MBP and is seeking advice on whether this would be a wise choice.

    In response, dmccloud, a more experienced member of the forum, commented that upgrading to a newer Apple Silicon model would be a much smarter move than sticking with another 2015 model. This advice was well-received by other members, indicating a consensus on the benefits of newer technology.

    Stp479 acknowledged this suggestion, noting that they would now focus on looking for a MacBook Pro introduced in 2021 or later, along with the MacBook Pro 13-inch model featuring the M1 chip from 2020. This shows their openness to considering newer models that would likely provide a better user experience.

    Another member, FreakinEurekan, weighed in with a different perspective, suggesting that if the 2015 MBP was available for free, it could be worth considering, but emphasized that spending any significant amount on it would not be advisable. This highlights the sentiment that while older machines can be useful at no cost, investing in outdated technology might not be the best decision for long-term needs.

    Ultimately, the discussion underscores the importance of exploring newer technology options, particularly when they promise improved performance and support.

  • MacBook Pro 14″ (M4, 2024) Powers Off When Plugged In; MagSafe Flashes Amber

    **Model & History**

    The device in question is a MacBook Pro 14″ from late 2024, featuring the M4 chip and is a base model. Approximately four months ago, a tea spill occurred on the keyboard. A local repair shop performed a cleaning but did not replace any parts, and the MacBook has been functioning normally since. The battery remains in good condition, and it is currently running macOS Sequoia.

    **Current Symptoms**

    When powering up on battery alone, the Mac operates normally until the battery runs low. The system displays a message indicating it is running on reserve battery life, followed by the yellow-triangle warning screen stating that the macOS version on the selected disk needs to be re-installed. However, if I go to Recovery and reboot the macOS, the Mac resumes normal operation. The complications arise when any external power is connected.

    Regardless of whether I use an Apple 140 W charger with MagSafe 3 or a known-good 96 W USB-C brick, the MagSafe LED blinks amber for about one second before the laptop shuts off completely. This behavior occurs across both USB-C ports. Upon reconnecting the charger while the Mac is off, I briefly see a blink, but nothing happens after that. Disconnecting the charger allows me to boot once again using the remaining battery.

    I have tested three different chargers and two MagSafe 3 cables while cleaning all ports with 99% isopropyl alcohol and allowing them to dry for 24 hours, but the issue persists. **What I’ve Ruled Out / Measured**

    To determine the problem, I have ruled out the charger and cable as possible issues, visually inspected the MagSafe DC-in board for damage, verified that the battery fuse is intact, and noted that the liquid-detection lock does not correspond with the hard power-off incidents. **Suspicions from Research**

    Based on my findings, potential causes include a faulty RAA489900/RAA489901 charger IC (U7200) or a shorted PPBUS bulk capacitor. While less likely, issues could also arise from both CD3219/3220 USB-C PD controllers or the ideal-diode MOSFET pair.

    The repeated hard shut-offs may have resulted in corruption of the Signed System Volume, hence the yellow-triangle warning. **Goal**

    My aim is to identify the exact issue and assess whether a U7200 re-chip or capacitor swap would be a worthwhile solution if that proves to be the root cause. I appreciate any schematics, voltage points, or any other insights you can provide. Thank you!

  • Differences in Apple OEM USB-C Cables: A Discussion on MacRumors Forums

    I recently stumbled upon some information regarding USB-C charging cables, which has sparked my curiosity about their differences in capability. Upon closer examination, I’ve learned that there are variations between cables that may appear identical. As the owner of both a 12-inch MacBook and a 15-inch MacBook Pro, I find myself needing to discern which cable is suitable for each device, something I had never considered before. An interesting point is that Apple is now offering a new 1-meter USB-C cable, sold alongside the latest iPads, yet it still lists compatibility with the 15-inch MacBook Pro.

    This prompts me to question whether the 2-meter cables included with the 12-inch models differ from those bundled with the larger models or those sold separately by Apple. The article I reviewed mentions that the serial numbers on these cables might indicate their intended use. For example, cables with serial numbers starting with C4M or FL4 are meant for the 29W or 30W USB-C Power Adapters, while those beginning with DLC or CTC correspond to the 61W or 87W models. This suggests that the differences between cables might be more than just cosmetic; there could be functionality variations that impact how effectively they charge devices.

    While it’s possible that the discrepancies in serial numbers serve mainly as internal identifiers for warranty purposes, I can’t help but wonder if there are real differences in performance and optimization among various USB-C cables. This realization raises further questions about the importance of selecting the right cable for maximizing the capabilities of my devices.
