Rode Uber Pool to UCSF Laurel Heights. Breakfast from The View Cafe: egg, cheese, and bacon on croissant, coffee with half and half. Identity retheme work all day. UCSF shuttle from Laurel Heights to Mount Zion. Lunch at My Father's Kitchen: beef noodle soup. UCSF shuttle from Mount Zion to Parnassus. Ran an errand. Worked from Kalmanovitz Library. Rode Uber Pool home. Dinner at home with Patrick: Good Eggs linguine with pork and beef ragu. Continued with confirming sanitization of the SSD on my old iMac in preparation for selling it. My last attempt to get my very old copy of DiskWarrior to mount from CD-ROM using a wired keyboard failed. Downloaded Disk Drill and Data Rescue to a USB drive from my MacBook Pro, then removed the USB drive. Started the iMac from that USB drive. Ran a latest trial version of Disk Drill on my old iMac. A search for recoverable files took about 45 minutes for a 1 TB drive. Began a second search using a demo version of Data Rescue 3 (old).
