Download the New Version for Apple Big Sur

Apple has recently released a new version of its operating system, Big Sur, which promises to bring many exciting features and improvements to Mac users. However, some users have reported experiencing significant slowdowns when using this new operating system on older Mac models.

According to reports, those who own 2011 or earlier Macs may encounter unacceptably slow graphics performance with Big Sur. This can result in lengthy delays when switching between apps or performing other tasks that rely heavily on graphical processing. For example, minimizing a Safari window takes significantly longer on unsupported Mac models compared to newer machines.

One of the main issues is the lack of 'graphics acceleration' support for non-Metal graphics cards. This means that many users who own older Macs may not have access to this feature, which can greatly impact their overall user experience.

Another problem is that some software functionality has been stripped from Big Sur, making it difficult or impossible for unsupported Mac models to run certain applications. Furthermore, Apple has locked out these older machines from running the stock installer of Big Sur and prevents them from receiving OTA upgrades via Software Update.

Despite these challenges, there are still ways to make unsupported Mac models work with Big Sur. For example, users can search for and reinstall missing graphics acceleration drivers or update their WiFi/BT cards to ensure better compatibility.

It's worth noting that some Mac models have been officially supported by Apple since the release of Big Sur. These include the iMac12,x and Macmini5,x series, which will receive support starting with OCLP 0.2.5. Additionally, users who own Early-2009 or newer Mac Mini or white MacBook, Late-2008 or newer MacBook Air or Aluminum Unibody MacBook, and Early-2008 or newer Mac Pro, iMac, or MacBook Pro can expect improved graphics performance with Big Sur.

In conclusion, while Big Sur has brought many exciting features to the table, it's clear that some users may encounter significant challenges when using this new operating system on older Mac models. However, by searching for and reinstalling missing drivers or updating their hardware, users can still make the most of Big Sur on their unsupported machines.
