In perfect condition. Fully upgraded with 256GB Samsung Pro 850 SSD. Quite fast. Interior fully cleaned. Many years of good service remaining.
macOS Big Sur is installed (the last macOS supported by this iMac by Apple) Quite fast. Browser works on all websites.
Latest macOS is also installed (so this mac can boot 2 different macOS) using a popular patched macOS tool called OCLP to install latest macOS on older macs. Runs perfect but UI is a little slower than Big Sur upon initial login. After initial login processing is done in a min or so. Its quite fast so just sleep and wake up usage without logging in constantly is reaonsabley fast. Anyway, its good for future proof.
Basically run like the latest macs for fraction of the price.
Need to provide own keyboard+mouse. Any will do. Often $5-$10 or free available in local online markets.
