Update Old Imac

Testing conducted by Apple in July 2020 using pre-production 3.6GHz 10-core Intel Core i9–based 27-inch iMac systems with 128GB of RAM, and shipping 3.6GHz 8-core Intel Core i9–based 27-inch iMac systems with 64GB of RAM. Tested with MATLAB and Simulink R2020a Update 4 and Parallel Computing Toolbox using a vehicle dynamics model. Apple updated the 21.5in iMac in August 2020 but rather than upgrading the processors all the company did was switch out the old-fashioned hard drives that used to ship as standard for faster SSDs.

Update Old Mac Os

Apple today released iOS 14.4.1, iPadOS 14.4.1, macOS 11.2.3 Big Sur, and watchOS 7.3.2 to address a concerning WebKit vulnerability. Over the weekend, Apple quietly discontinued the iMac Pro and is selling off the remaining stock. Will it return in some form, or was it just a stopgap while Apple redesigned the Mac Pro? If you’ve had trouble scrolling through email messages in Mail on your Mac, Adam Engst has a possible explanation. The mystery of Dustin Curtis’s locked Apple ID has been a hot topic in the Apple community, and we try to tease out what happened. Finally, if you’re missing MagSafe for your MacBook, Adam takes a look at magnetic USB-C charging adapters to see how they compare. Notable Mac app releases this week include iMovie 10.2.3; BusyCal 3.12.4; Audio Hijack 3.8.4 and Piezo 1.7.3; Final Cut Pro 10.5.2, Compressor 4.5.2, and Motion 5.5.1; DEVONthink 3.6.3; Transmit 5.7.2; Zoom 5.5.5; and Safari 14.0.3.
