Pick up in Markham near Highway 7 & 48.

• Runs Catalina 10.15.6 but can be updated to newer versions of macOS using OpenCore Legacy Patcher.

• 3.1 GHz quad-core Core i7-3770S, 8 gigs memory, 1 TB HDD.

• NVIDIA GeForce GT 650M graphics with 512 MB VRAM.

Excellent condition. Works perfectly. Screen is spotless with only one speck on glass.

Comes with: Apple USB Keyboard (w/ numeric keypad) and Magic Mouse 1 (2x AA battery powered, missing battery cover but works)

Affordable Catalina-class desktop that can even tinker with Windows 10 and 11. I've seen a few 2012s for sale running Windows 11.

What is a 2012 iMac good for?

• Handles the current Microsoft 365 web apps, Slack, 30-tab Chrome sessions, and 1080p YouTube without breaking a sweat.

• Decodes 1080p h.264 smoothly

• Photo editing: Lightroom Classic 13 (Catalina-compatible) still exports RAWs in reasonable time; iMovie 10 edits 1080p footage acceptably.

• Gaming: GT 650M equals ~Intel UHD 630; e-sports staples (CS:GO, Rocket League) hit 60 fps at 720p–900p

Is it worth installing Windows 11 on this?

Windows 11 mandates TPM 2.0 and a 2018-or-newer CPU. The 2012 iMac ships with neither, so installers must bypass checks (e.g., Rufus BIOS/UEFI media).

Performance under Boot Camp is roughly on par with macOS Catalina. It's fine for Office, web, and 1080p video, but gamers must drop to 720p.

Feature gaps:

• No firmware TPM = Windows 11 shows a watermark and may block cumulative updates.

• Boot Camp audio drivers are flaky post-23H2; expect manual tweaks.

• Future Windows 11 24H2 builds tighten the bypass loophole.
