2001: PowerBook G4 used up to 2011 (10 years)
2001: PowerMac G4 (dual 1GHz) used up to 2013 (12 years)
2008: MacPro still in use today
2009: Mac mini (server purpose) used up to early 2023 (13 years)
2011: MacBook Pro put aside late 2023 (12 years)
2022: got used Mac mini (2014) replaced the 2009 server, in use today
2023: got used MacBook Pro 2019, in use today
All of these machines are still here and still work. Before that, the Windows PC's I had are all broken.
So... at least 10 years or more and I hope that when I get my Apple Silicon Mac's they also will function for at least 10 years.
