Without Rosetta, you lose all of your old PowerPC applications. Mountain Lion now feels like it has matched it as far as overall performance goes, but as Dan Knight mentioned, Snow Leopard enabled PowerPC applications to run courtesy of Rosetta. I see Tiger, then Snow Leopard as something of “lines in the sand” in which large numbers of Macs can/will never cross.ĭan Bashur ( Apple, Tech, and Gaming): Snow Leopard is still the OS for Intel Macs bar none. We will see many lower-end Intel machines running Snow Leopard many years into the future. Steve Watkins ( The Practical Mac): Simon hit the nail on the head: I believe Snow Leopard will be to Intel Macs what Tiger is to PPC. Snow Leopard is the slick and fast Intel OS, much as Tiger was to the PPC platform. Lion was quite a bit slower than Snow Leopard, and while Mountain Lion brought back some of that speed, Snow Leopard really was a slick and streamlined OS. My first impressions were “wow, this thing is fast.” It was so much faster and a lot more stable than Leopard on my MacBook.Ī few weeks after, I upgraded to Lion, and then on launch day I upgraded to OS X 10.8 Mountain Lion. Being a PPC Mac user for a long time, I had no experience of Snow Leopard until 2012.

Leopard was great, but Snow Leopard blew me away. I bought it in 2012 and picked up a Snow Leopard disc only a few days after purchasing it. Simon Royal ( Tech Spectrum): My MacBook – an early 2009 model – shipped with Leopard. By eliminating legacy PowerPC code, Snow Leopard needed less drive space and ran some things faster than ever, as well as introducing some new technologies to the Mac. That came to an end with OS X 10.7 Lion, so for a lot of Mac users with older software, Snow Leopard will always be the last version of OS X to run those PPC apps.īut there were improvements as well. It still worked like earlier versions, and although it didn’t support PowerPC Macs, it still ran PowerPC software. And with 10.6 Snow Leopard, it completely left PowerPC Macs behind.įor PowerPC users, it was an insult, but for Intel users, Snow Leopard would become the last traditional version of OS X. With OS X 10.5 Leopard, Apple had shipped a universal binary version of its OS that could run on either hardware platform. Macs had uses PowerPC processors from the System 7.1 era up until 2006, when the first Intel-based Macs arrived running a special Intel-only version of OS X 10.4 Tiger.

While the requirement to upgrade a Windows 10 device to Windows 11 is only that the PC be Secure Boot capable by having UEFI/BIOS enabled, you may also consider enabling or turning Secure Boot on for better security.Dan Knight ( Mac Musings): It’s hard to believe that it was just three years ago that Mac OS X went Intel only. Here are a few links to information from some PC manufacturers to help get you started:

If you are unsure how to make any necessary changes to enable the UEFI/BIOS, we recommend that you check your PC manufacturer’s support information on their website. If so, you will need to choose for UEFI to be the first or only option. In some cases, there are options to enable both UEFI and Legacy/CSM. To change these settings, you will need to switch the PC boot mode from one enabled as “Legacy” BIOS (also known as “CSM” Mode) to UEFI/BIOS (Unified Extensible Firmware Interface).

To access these settings, you can consult your PC manufacturer’s documentation or follow these instructions: Run Settings > Update & Security > Recovery and select Restart now under Advanced startup. From the next screen, select Troubleshoot > Advanced options > UEFI Firmware Settings > Restart to make changes. Firmware, often called BIOS (Basic Input/Output System), is the software that starts up before Windows when you first turn on your PC.

Most modern PCs are capable of Secure Boot, but in some instances, there may be settings that cause the PC to appear to not be capable of Secure Boot. These settings can be changed in the PC firmware.

Secure Boot is an important security feature designed to prevent malicious software from loading when your PC starts up (boots).

This article is intended for users who are not able to upgrade to Windows 11 because their PC is not currently Secure Boot capable. If you are unfamiliar with this level of technical detail, we recommend that you consult your PC manufacturer’s support information for more instructions specific to your device.
