That’s a great point about older systems. I’m pretty thrifty and often tend to try to wring a couple extra years out of my Macs. Lots of first-hand experience with Sequoia on OCLP for various Intel-era Macs running GarageSale. I’ve found GarageSale to work exceptionally well on old Macs, although OCLP does require considerable babysitting, especially involving the installation of root patches after a MacOS software update has occurred. Overall, I’ve found it to be worth the time involved, especially when the older Mac has lots of RAM and a reasonably fast processor.
Related to this, I made a post a couple of years ago and Ilja, one of GarageSale’s developers had an excellent response detailing what hardware factors are most relevant to GarageSale performance. He basically said it comes down to RAM (more is better) and single-core chip speed. That information was really helpful, as it validates the cost savings of using slightly older or entry-level Macs, as the multi-core processing advantages that cost lots of extra money on higher-end Macs turn out not to be all that relevant to achieving snappy GarageSale performance.
