![]() She ran a full Windows OS (Windows 11, no less) on an older iMac (desktop) machine. One of my AutoCAD students recommended it to me. I have always wanted to run native macOS on the MBP, as I use it for other stuff music, writing, and other creative dark arts I am working on (Hehe), but I also run AutoCAD for Mac on there, so I wanted to keep in touch with AutoCAD on macOS as well. ![]() But how do I get around the issue of TPM not being supported by my MBP? It provides a level of security I must have today. In 2016 TPM version 2.0 - the current version as of this writing - became standard in new PCs” TPM has been around for over 20 years, and has been part of PCs since around 2005. ![]() Typically, it's a separate chip on the motherboard though the TPM 2.0 standard allows manufacturers like Intel or AMD to build the TPM capability into their chipsets rather than requiring a separate chip. It's used by services like BitLocker drive encryption, Windows Hello, and others, to securely create and store cryptographic keys, and to confirm that the operating system and firmware on your device are what they're supposed to be, and haven't been tampered with. “ A TPM (Trusted Platform Module) is used to improve the security of your PC. So, what is TPM? I did a bit of research, and on the Microsoft Support pages, I found this:. This was a bit of a game-changer, as I run most of my Autodesk Windows-based apps on the boot-camped Windows partition on the MBP. After running the Windows PC Health Check from Microsoft, I was told that my eighteen-month-old MBP would not run Windows 11 via Boot Camp. My MacBook Pro (MBP) has an Intel processor that does not support TPM 2.0, which is required for Windows 11 to run. That was until Windows 11 became available and threw me a bit of a curveball. This particular blog series will be somewhat Apple-based as, until now, my MacBook Pro has always been my go-to laptop, and I have been running Apple Boot Camp to dual partition my MacBook hard drive 50% macOS and 50% Windows. I also run various pieces of Dell hardware, just for full disclosure. Some of you may not, and each to their own, but Apple has been my tool of choice for some time now. I run a MacBook Pro, iPad Pro and an iPhone. Tl dr: Rosetta 2 doesn't work, will not work, and you probably won't like it if it does work.I’m a bit of an Apple aficionado, and I love the Apple ecosystem. web browsers that dynamically compile Javascript into native code), but will be slow. It will have to fall back on just-in-time translation, which is supported (because it needs to work with e.g. Apple's approach results in a really slow launch time the first time, and then smooth sailing after that, while Microsoft's approach slows down the app experience for a while until the entire app has been translated and cached.Īnyway, the problem with virtualization is that there is no good way for Rosetta 2 to pre-compile the entire virtual machine. This is in contrast to Microsoft's approach, in which an app is translated as it is being run. QEMU.Ģ) Another reason why Rosetta 2 appears to be so fast is because it translates the entire app when it is first launched. So Rosetta will have no inherent speed advantage over other emulators, e.g. The problem is, virtualization is one area where the app spends most of its time running code that isn't built into macOS. The translated app will run native versions of these OS functions, and only the app's own code will be slowed down by the translation. Applications tend to spend the bulk of of their time calling the OS's functions-drawing screen elements, handling I/O, calling CoreFoundation functions, etc. An x86_64 Cocoa app translated under Rosetta 2 transforms into an ARM app. Which is why UTM has to rely on QEMU for emulation.Īnd even if Apple adds support for virtualization, performance will be terrible for at least two reasons:ġ) A key reason why Rosetta 2 appears to be so fast is because it is emulating (translating) only a small part of the code being actually run. Click to expand.Apple explicitly says Rosetta 2 does not support virtual machines.
