Adding a filesystem format change might make me decide that this is a bit too risky for this particular device. Deciding to turn on encryption has one set of implications, and we've had our hands on HFS+ CoreStorage encryption since OS X Lion, so there aren't many surprises left. That's what I'd be telling myself had this happened to me, but I'd certainly have appreciated some warning. Did I want my expensive RAID device to be my APFS Guinea Pig?ĪPFS is supported atop RAID devices, so this conversion will surely work out just fine. Potential hazards of converting your data volumes to APFSĪpple has demonstrated that the conversion from HFS+ to APFS has gone pretty smoothly, but there are a few scenarios where you might want to give some serious thought to that kind of conversion. Rather than simply converting the volume to a CoreStorage Encrypted volume and keeping the HFS+ format, macOS converts the volume to APFS with no warning, and then enables encryption. Take any HFS+ formatted volume that does not have an installation of macOS on it (that part is key), right-click on the volume in the Finder and choose the option to encrypt it. It is apparently possible, however, and I was able to confirm this behavior on my test system. Oddly, though, CCC, Disk Utility, and Terminal all agreed that his HFS+ volume was now an APFS Encrypted volume. This is an easy way to enable encryption on a volume: plug in a password, verify, add a hint, done! There's no OS on it, so he simply right-clicked on the volume in the Finder and chose the option to encrypt it: He had an HFS+ formatted 16TB RAID device, and had always intended to enable encryption on that volume. Meaning, it's pretty darn nice inside as well, with fancy stitched leather, real wood trim, a suede headliner, massaging front seats, rocking Bose audio setup and lots of customizable screens.One of our users made a startling discovery this week after upgrading to High Sierra. On the inside, it gets the Denali Ultimate layout done up in slightly different materials but no Super Cruise. Upping performance are Multimatic DSSV dampers and exclusive springs that contribute to a 2-inch lift, increased wheel travel over the regular AT4, a two-way transfer case and some bigger underbody shields. More interesting is the arrival of GM's Super Cruise system that'll be standard on Denali Ultimate and available on the Denali, providing hands-free, trailering-capable operation on certain premapped highways.įor off-road enthusiasts who also enjoy the finer things in life, GMC is debuting a new AT4X Sierra trim that gets improved off-road chops over the standard AT4, as well as a more plush cockpit. When it comes to active safety goodies, GMC equips every Sierra with forward collision warning with automatic emergency braking, lane-keeping assist, pedestrian detection, auto high beams and a HD backup camera. Soft leathers, real wood and aluminum trim make the Sierra Denali Ultimate's interior feel high end. Add all those screens together and you can have more than 40 inches of customizable digital real estate in the 2022 GMC Sierra. On top of that, a 15-inch color head-up display is available, which also happens to be customizable. The gauge cluster is now also a screen measuring 12.3-inches and offers multiple views to choose from. And on the top Sierra trims, there's a new 12-speaker Bose audio setup.
