I got this iMac for free.

iMac (21.5-inch, Mid 2011) - Technical Specifications - Apple Support

support.apple.com

It does not boot, "BEEP BEEP" ... and without the glass ...





it could be my file server for the other macs

Not a 100% but IIRC there is a bunch of LED for troubleshooting purposes in the Logic Board

All the cables were unplugged, and the hard drive and SIMMs were removed.
I managed to get it to boot; it’s now (as expected) stuck at the “?”.

Next, I’ll install a new glass panel and an SSD.

However, as with many older iMacs, I’m having trouble creating a bootable macOS USB installer from my Apple Silicon M1.

I’ll try using an Intel Mac instead. If anyone has a solution they’ve personally tested, I’d appreciate a suggestion.
