Not much has changed except wallpaper (minimal) and various stuff on the desk (also minimal). Don't recall the last time I put my Mac setup on here.
Anyway, the six displays are attached to a 2009 Mac Pro 5,1 (4,1) running Sonoma 14.6.1. The Macs underneath the desk are a PowerMac G5 Quad to the far left (awaiting shipment to someone else), 2006 Mac Mini (left), 2023 M2 MacBook Pro (work issued, on the right), 2015 MacBook Pro (work issued, on the right behind the M2) and a Lenovo Thinkpad (far right, not sure what year).
On the desktop is a 2011 MacBook Air and on the far right my 2003 17" PowerBook G4.
I work from home so the 2009 Mac Pro and the 2023 M2 share a KVM switch. At the time I took the picture, it's a Saturday and so the M2 is off and won't restart until Monday morning. Hence the blank vertical monitors which the M2 also uses, but the Mac Pro does not.
PS. The vertical TV on the left has failing red and green LEDs so has this bluish cast in all the pics I take of it. But it was a Goodwill purchase for $15. That particular cast in the pictures is not present in actuality.
PPS. Oh yeah, next to the Mini is a 2006 17" MBP running Snow Leopard and a 2008 MBP running Sonoma 14.5.
