Copy and pasting this from my post/comment on a Gizmodo article (which apparently hasn't gotten "approved" yet) so excuse any chronological "inaccuracies". The only thing different is the amendment of the next sentence and the next sentence only, along with re-wording the following sentence so it makes sense......... I'll preface this by saying that I was invited to participate in the El Capitan beta program but never did download any of the beta releases lol. Because I was invited to participate, I was granted access to the GM, which I installed last night. Ran my next Time Machine backup, and installed 10.11 with no issues... until about a half hour later when the machine booted up and that’s where I ran into a bunch of brick walls (in a software/app compatibility regard). Lol, I was up for another hour or so updating as much as I can. This was expected, though, because it was only about 4-5 hours after I got the email when I actually got the chance to download the installer and run it, and not many apps were updated for 10.11 compatibility ahead of time (most notably, Xtrafinder *sad face*). One big issue I’ve run into - which I don’t think is much of a 10.11 issue as it is the way I set the darn thing up - is with the new SIP setup. I’ve been using cDock for the past year with Yosemite, and apparently with El Capitan there’s this “protection” (rootless) thing, I reckon for the end-user’s benefit, that will require the user to disable it, install some sort of... proxy or... helper file/tool into the kernel and then re-enable the “protection” so apps like cDock can work. I know exactly what I need to do JUST to disable/re-enable SIP (“csrutil disable” in Terminal), but for some reason, I can’t access recovery on my boot drive. A heads up: My machine is a mid-2012 MacBook Pro 13” (the 2.9GHz setup) My boot drive is an SSD. Has the OS partition and a Recovery HD partition... and that other first partition that’s like 325kb or whatever, I forgot. I’ve done the optical drive “mod”, where I have another hard drive installed into the machine (its the original Toshiba 750GB HDD) that I use as a scratch disk for video editing and whatnot. I also use it as a fail-safe, in case for some magical reason I can’t boot onto my main drive, meaning it does have a working copy of OSX 10.9.5 on it. Purposely not updating it because I need a “way back” into that UI, lol (not really). There’s a recovery partition on that drive too, which shows up in the boot menu as well as diskutil -list, of course. Anyway, the recovery partition on my SSD shows up when I run the diskutil -list command as disk0s2 (IIRC), but when I run the command in recovery from the HDD, or my Time Machine disk, at the foot of the diskutil -list results says “Macintosh SSD...” (that’s what I named it) “... [insert UUID here] is locked and encrypted” or something along those lines (perhaps because I have FileVault enabled on the SSD), which makes me wonder if the reason that I can’t get to the recovery partition on my SSD is because the drive is encrypted at the boot menu(???)... then I read something about reverting corestorage or something... blah. Idunno. But I DO know that I can’t get into my “active” recovery, at all. I don’t recall having this “issue” before I updated to 10.11. Any tips? I was gonna disable FileVault but I had to get some sleep, so I left it alone, lol.
