It's mandatory that you enter them accurately. See post #7 below to view screenshots of what it's like to use the modified grub shell to make these changes. Step #2: Boot into a modified grub shell by using your Big Sur Installation USB you created previously. The last 5 help improve USB 2.0 and 3.0 port functioning and are highly recommended. The first two (CFG Unlock + DVMT) are mandatory if you want to install Big Sur and potentially use a 4K monitor via DP output and HD4600. Again, take your time, enter the correct numbers to make the changes. I've used larger fonts so you can see the numbers easily and not enter any wrong values. Step #1: Print out the file (attached below) before making the changes via a modified Grub shell you've booted to from a USB.

This guide doesn't got into specifics of those other models, only the following: ![]() To discover the offset values for the 3020 or 9020M you'll have to extract the BIOS and search for them on your own. These do not apply to the 2 Dell Optiplex 3020 form factors or to the micro sized 9020M models. I've created a chart which includes the offsets that are specific to the Dell Optiplex 7020 A18 BIOS and 9020 A25 BIOS.įor only the USFF, SFF and MT form factors. Oh and YMMV with upgrading from Mojave or Catalina to the next OS like Big Sur or Monterey.Building a CustoMac Hackintosh: Buyer's GuideĬhanging the Dell OptiPlex Hidden BIOS/UEFI Settings Humorously, if some woman can sue Kraft for falsely advertising Mac & cheese (see the pun?) only takes 3 minutes to serve when she says it takes longer, because you have to mix the powder and let it set… well, with Apple’s updates, wisdom shows their legal weight using the word “About…” to protect them from providing a operating system that should, in this era, display accurate estimated time. ![]() What showed as “About 35 minutes” from installation actually took over three hours to get to a login screen. While it was mostly uneventful, I am reminded of Apple’s poor “time remaining” display isn’t very reassuring. Speaking of moving from Catalina…I had to move a user from Mojave up, and went right to Monterey. Like me, and my 2012 Mac Mini, we’ll just not.Ītleast those of us who can’t update, can move to OpenOffice or LibreOffice, the latter I use and support. I have to scramble to get some of my users off Catalina, and some can’t as their older hardware won’t support past Catalina. I was told that Catalina support from Apple end’s this month, so this update information is likely related. Some of the supporting details in “ Why You Should Upgrade (On Your Own Terms)” (4 September 2015) may seem dated, but its key points are as valid now as they were 7 years ago. Upgrading is a pain, I know, but it’s a necessity of modern life. At some point, that may become a problem. If you continue to use Catalina, your Office apps will still work fine but won’t receive enhancements, bug fixes, or security updates. The October 2022 update (16.66) was the last build of Word, Excel, PowerPoint, Outlook, and OneNote for users running Catalina. macOS 12 Monterey and macOS 13 Ventura are fully supported. That applies to Office for Mac 2019, Office for Mac 2021, and Microsoft 365 (see “ Microsoft Rebranding Office to Microsoft 365,” 17 October 2022). Microsoft has announced that the company’s productivity suite will receive updates only if your Mac is running at least macOS 11 Big Sur. If you use Microsoft Office in macOS 10.15 Catalina, there’s yet another reason beyond the lack of Apple security updates to consider upgrading soon.
