My biggest beef with the new MBP TouchBar is how horribly slow Keychain has become. * When a login form is shown in Safari, it takes 2-3 seconds before the username and password are prefilled. Safari just hangs (beach ball) in the meantime. * Searching in Keychain Access is horribly slow. After a search term has been entered, it takes 4-5 seconds before the search results are shown. Keychain Access just hangs (beach ball) in the meantime. And it is made worse as searching also starts during typing, so you can type... but the text won't show up. And Keychain Access simply hangs. And after the 4-5 hang is over, it starts hanging again as you've entered additional search terms. * In Keychain Access when you've finally gotten to the entry you wanted, copying the password to clipboard is another 2-3 seconds wait. With appropriate hang (beach ball). This has been going for many users on this machine. Apple doesn't confirm that this issue exists, keeps suggesting to reinstall their machines and offers replacements to others -- which obviously doesn't help. Users testing macOS High Sierra beta's report small improvements, but still nothing significant. [speculation] I suspect the Secure Enclave is to blame here, some design issue with the hardware. High Sierra appears to do heavy caching of the Keychain, to work around this hardware issue. [/speculation] [edit] Issue #2 with this machine is that Spotlight randomly stops working. You can open Spotlight (CMD+Space), but you can't type your query -- it doesn't respond to key pressed. You have to `killall Spotlight` from the Terminal to fix this. Issue #3 with this machine is that the keys are too close to the screen when closed. You can see an "imprint" of the keyboard when opening. This will probably cause damage to the screen's coating in the long rung and thus reduce the machine's lifetime (damaged screen). Issue #4 is flaky Bluetooth radio. Multiple times throughout the day my Apple Magic Mouse, Apple Wireless Keyboard and/or Sony headset will disconnect. Issue #5 is slow wake from sleep. I've had multiple wakes from sleep taking over 20 seconds -- leaving the screen black while resuming. The repair center blames high memory usage (paging). However my previous 2013 MBP (also 16 GB) didn't have the same issue, and my use hasn't changed. Issue #6 is that the machine sometimes crashes when plugging in the Apple USB-C HDMI Multiport adapter. That's a great start of a presentation having a room full of people.
