Did I accidentally gave my 1Password master password? Thrice, no luck. I typed my usual local password thrice, no luck. Maybe I missed a checkbox during setup (unlikely), and maybe it was nothing new (I don't think so), but I only realized this when I needed to sudo on the new OS for the first time. Actually these surprises motivated me to write this post.įirst, the OS seems to default to using the iCloud password (i.e., the Apple ID password) as the local account password now. Nevertheless, I was caught by surprise at least twice, due to subtle user-facing changes in the OS. I haven't set up my mail accounts 4 and printer yet, but hopefully they will work, and just hopefully Apple Mail finally got it right this time™ and won't ask me to reauthenticate with Gmail all the time. Those were basically all I had to deal with. Anyway, I quickly paid to upgrade to v10.2.0 (cost of free OS upgrade, geez), and it ran happily afterwards. The only distratrous incompatibility I've seen lies with Mathematica 9 codesign -vvvv Mathematica.app on the v9.0.1 app bundle says resource envelope is obsolete (version 1 signature), and OS X downright refused to open the app, offering me no option other than trashing the app, even when I temporarily set Gatekeeper to "Any". Some of XtraFinder's features 3, including my most needed auto resizing columns, don't seem to work on El Capitan yet, and I'll have to contact the developer soon. I needed to brew reinstall pyenv -HEAD because an OpenSSL fix for El Capitan hasn't made into a release yet. Thus far, most of my programs and applications seem to work just fine on El Capitan. It was the first time I used it outside a VM to provision an OS from almost scratch, and I'm really happy with it. With data and state info ready, reinstalling programs is also easy, thanks to my recently finished automated provisioning system. rsync is really good at this stuff (I affectionately alias rsync -avP to r during transfers in and out), and it is simply amazing at dropping the right stuff at the right place, including data deep down ~/Library/Containers, without interfering with the existing structures 2. Therefore, what I did instead was to rsync out all my valuable data and state information 1 to an external drive, wipe the internal drive clean, install new OS from scratch, then rsync everything back in. To be accurate, I'm not really upgrading in place - I always perform a clean install for each major OS upgrade to avoid subtle breakage later on. I upgraded to El Capitan last night, and the experience is pretty painless.
