This is just a rant. There's nothing useful here. I need to rant right now and this seemed like as good a place as any. Feel free to ignore this thread. I bought my first iMac in 2006 when I finally got sick of Windows. I never regretted switching. The only problem I ever had with it was when the Ethernet died, and I solved that with a cheap Ethernet-to-USB adapter. It worked fine and did what I wanted it to. OS X 10.6.8 was the last OS I had on it, since I decided not to upgrade to 10.7, and after that nothing else would install on it. Now it's not compatible with my iPad or my iPod, and there are things it won't do, or does poorly because the hardware is so out of date. So I bought a new 21.5-inch 4K iMac with the i5 chip, 8 GB RAM, and 256 GB SSD. It arrived 18 1/2 hours ago and I've been pulling my hair out ever since. I HATE the damn thing! First, I could not connect my external backup HD to fetch files I wanted, because the HD uses Firewire and the new iMac does not have firewire. I'm going to have to get an adapter. Then I could not use Migration Assistant because the OS versions are too far apart. I used Air Drop from my iPad to bring some pictures over, since the improved screen resolution was one of the reasons I wanted to upgrade. But neither Preview nor Photos will allow me to set the default to "Open pictures at full zoom to fill the window." The pictures have enough resolution to look beautiful zoomed to the full screen, but I have to zoom each picture one at a time. And I cannot get the computer to recognize either my nice Logitech wireless solar-powered keyboard or my Bluetooth trackpad, so I'm stuck using the really crummy little Apple keyboard with no number pad and the "magic" mouse, which to give it its due is better than other mouses I've used, but nowhere near as nice as my trackpad. The photo app I used on the old Mac has in the intervening years been "improved" to the point that I cannot use it. I tried to download a card game from the Mac app store and all I got was a text file full of gibberish. I downloaded Gimp for pictures, and it would not run. At least I was able to get Chrome and NeoOffice, and use iCloud to migrate a few files over. I'm sure there will be other exasperations. I'll probably like it once it's all properly set up, but for now I hate this thing, and my only consolation is that I can take it back and get my money back. If you ask me now, that's probably what I'm going to do. I know from experience that it gets better, but right now it seems as though they've done EVERYTHING wrong. Thanks for letting me rant. BTW, in contrast, I love my new iPad Pro (128 GB, Wi-Fi only) and will definitely be keeping unless it develops a defect. It could almost, but not quite, replace the desktop computer. I remember in the early 1970's when I got a kitten. Home computers did not exist. I wrote letters sitting in an easy chair with a clipboard and ball-point pen, and the kitten would climb into my lap and try to steal my pen. Everything was so much easier. I'm addicted to gadgets, but I don't think they actually make my life any better.
