I have owned the computer for just shy of a year, and had put off "upgrading" to Mojave until work was through xmas eve. That was the last time I ever saw my 'Mac,' or ANY of the files I had accumulated since its purchase the prior holiday season. The 'tech support' got to it right away via a live chat several times (8 total) and even took two trips to the apple service provider (an apple store) and the universal lack of knowledge and experience could offer no solution to their obviously wonky software. Despite a "technical bulletin," it was weeks before I was finally able to limp along until I could afford a replacement (NON Mac OS) that will hopefully be a better fit instead of charge for everything, give them half and make them feel grateful. Sure, I could have spent another 500 for a new replacement but WHY???? Apple doesn't care about rank and file users. They make their money elsewhere and given the loss of recent consumer protections and our 'China' trade thing I don't hold hope for any improvement any time soon. Sell sell sell. Or not but this is a flawed business model. At the end of the day I am out so much of my work as to make me wonder why I thought the "iCloud" back was a backup. Or why I assumed I was protected despite the hard sell on the backup service. WHAT? ITS NOT BACKED UP? Why am I paying for this service at YOUR BEHEST and its doesn't suffice for a backup? YOUR WORDS...ICLOUD BACKUP! sounds Mac to me-its proprietary we won't understand! Abandon faith all ye who enter MACworld iOS. :( its the code, stupid!
