2010 iMac running Sonoma? If so, how does it perform?
My wife has been using our late 2009 27" iMac with Intel i7 all these years. I bought the top end model at the time, which is why it's lasted so long, although I did have to
bake the video card to keep it going. It's still working, but I've kept macOS High Sierra on it to ensure I don't need to deal with trouble associated with putting a new version of macOS on such old hardware. I really have zero time to spend on that. I needed a "set and forget" solution.
High Sierra still works well on that older Mac hardware, bBut the main disadvantage of using such an old OS is that eventually you don't have good web browsing and modern security options. For that reason, I recently bought an M4 Mac Mini (not Pro) with 24GB of RAM and a 2TB SSD from the Apple Refurb store (and saved a bundle!) and just installed it last night. To make that upgrade fast and easy I connected my
SK Hynix 1TB SSD thumbdrive (shockingly fast for non-Thunderbolt) to make a Time Machine backup of the 2009 iMac (did that overnight because it's USB-2.0), then when the M4 Mac Mini arrived last night, I connected the thumbdrive to it and also the old keyboard and mouse. I then connected a 2012 Apple Thunderbolt Display that my wife got FOR FREE from her workplace in the past (a hospital, which sometimes gives away old computers when doctors leave for another hospital). Not Retina, but 1440p is nice, and it has a camera and great speakers too. The Time Machine restore went perfectly, with nearly 1000MB/s speeds, making the 950GB data restore happen in much less than an hour. All said, a fabulous and timely upgrade.
I was laughing to myself thinking I might get 20 years out of that 2009 iMac, but my wife was recently talking to me about security and performance, so I decided to do the Apple Silicon update for her now. But hey, 15 years and 9 months of use isn't bad!
Sorry for mucking up your thread, but it all ties into the "Brainstorm" upgrade theme for me. Sometimes we each need a "brainstorm" to realize when it's time for a major upgrade!
