Hello, dear forum members,

I hope this message finds you well. Currently, I’m using macOS Monterey, but I’m looking forward to upgrading to an M4 Mac that will likely come with macOS 15.1 Sequoia. I wanted to ask about a specific issue related to the initial login process. At the moment, I’m using a Logitech keyboard, the Keys to Go 2, which does not function for initial login due to my FileVault being enabled.

As a result, I have to rely on my older Magic Keyboard from the Steve Jobs era, which operates on two AA batteries, to enter my password for initial login. The problem is that the Logitech keyboard does not pair with my Mac until after the system has processed the initial password and has been decrypted. I’ve also encountered pairing issues with other Bluetooth keyboards, including the Magic Keyboard, during the initial login. Given these challenges, I was curious if any enhancements or accessibility features have been introduced in Ventura, Sonoma, or Sequoia that would allow users to input the initial login password using a virtual on-screen keyboard.

This feature would leverage a mouse or trackpad, both of which tend to connect more reliably for this purpose. Such an addition would be invaluable, as it would free users from relying solely on the official Apple keyboard. Your insights on this matter would be greatly appreciated. Thank you!

I am seeking examples of MacOS applications that fail to run on Mac Pro models 3, 4, and 5 (or similar) due to the inclusion of AVX or AVX2 instructions. The failure scenarios can be diverse, such as an early refusal from an installer indicating the CPU’s incompatibility, or mid-workflow crashes and even kernel panics.

The primary criterion is that the failures should likely stem from the presence of AVX/AVX2 instructions. Additionally, I am interested in software that allows users to toggle AVX support explicitly.

This might be achieved through settings adjustments or command-line options, where users can choose to enable or disable AVX features. A key requirement is that these software samples need to be freely accessible.

Open-source software, demos, or trial versions are acceptable. However, samples from expensive software suites will not be useful since I do not have legitimate access to them.

For any software that does not fail simply upon execution, I would appreciate detailed step-by-step instructions to reproduce the issue. I am aware that the MacOS Japanese IME may contain AVX instructions.

Unfortunately, my knowledge of Japanese is limited, and I find myself clicking randomly on the keyboard. If someone can outline a reliable procedure to replicate the failure using the Japanese IME, that would be incredibly helpful.

Thank you for your assistance in this matter. As for potential candidates suggested to date, I will keep track of suggestions and their validation:

– Japanese IME (MacOS Catalina/Big Sur)
– Prime95 (Torture Test mode)

I frequently use Lightroom and plan to utilize Photoshop more, particularly focusing on denoise and AI features. Aside from photo editing, I engage in casual gaming.

Unfortunately, I wish there were more first-person shooter games available for Mac, as I would enjoy playing them more. Currently, I am weighing my options for RAM, specifically deciding between 24, 36, and 48 GB.

I believe there is a connection between the amount of RAM and the number of GPUs that isn’t immediately clear. Essentially, GPUs utilize shared memory, meaning that an increase in the number of GPUs also requires more memory for normal operation.

For applications sensitive to memory use, having 48 GB with 20 GPUs could be more beneficial than 32 GB with 32 GPUs, as it provides greater memory bandwidth per GPU. However, there’s a limit to how much memory GPUs can effectively utilize with software like Lightroom and Photoshop, and beyond a certain point, the benefits may diminish.

I acknowledge that I am not an expert in this field, and I welcome insights or corrections from those who are more knowledgeable. I am particularly interested in real-world performance comparisons for Lightroom and Photoshop.

For instance, consider the following configurations:

1. 24 GB with 16 GPUs
2.

24 GB with 20 GPUs
3. 48 GB with 20 GPUs
4.

36 GB with 32 GPUs
5. 48 GB with 32 GPUs

While it’s tempting to choose the highest specs, I wonder about the cost-effectiveness.

If the performance difference between options 5 and 2 is only 20% (for example, reducing processing time from 30 to 20 seconds), is the investment justified? My priority is to avoid freezes and significantly longer processing times, though a few extra seconds is acceptable.

I would greatly appreciate your recommendations and any thoughts you might have. Your feedback would be incredibly helpful.
