Since loading Big Sur on my 20019 iMac, every runs excruciatingly slow. I was hoping TechTool Pro 13 could rescue me, but my computer hangs both when trying to create an drive and when trying to create Protogo. In both cases, I get partway through the process, and then a complete and permanent freeze. Plenty of memory, plenty of storage. I once used TechTool Pro a lot, but recent versions have been disappointing. Please help!
