![]() ![]() This isn’t new, but is more important because of APFS. Only the macOS Installer can download and install firmware updates.This requirement has various implications: The company claims you must be connected to the Internet when upgrading macOS, and the macOS Installer uses the model number of your Mac to identify and download a firmware update specific to that Mac to enable it to recognize APFS. There’s no penalty for caution, and be absolutely certain that Macs are backed up before upgrading them once Apple’s initial bug fixes are out.įirmware Updates via the Cloud - With High Sierra, Apple is re-emphasizing how Macs get firmware updates over the Internet. Although we’re not hearing of major software compatibility issues, the move to APFS is a very big deal, and it’s entirely possible that some problematic scenarios won’t have been anticipated by Apple or revealed by the public beta test. Important High Sierra Changes for IT Adminsįor most individual users, upgrading to macOS 10.13 High Sierra won’t require much more than going through the steps in Joe Kissell’s “ Take Control of Upgrading to High Sierra.” But for those of you who manage Macs for an organization (or are just interested in how things work behind the scenes), there are some important changes that you should know.įirst, I want to reiterate that our recommendation for High Sierra is that most everyday Mac users don’t upgrade immediately, but instead wait for 10.13.1 or even 10.13.2. #1643: New Mac mini and MacBook Pro models, new second-gen HomePod, security-focused OS updates, industry layoffs.#1644: Explaining Mastodon and the Fediverse, HomePod Software 16.3 and tvOS 16.3, GoTo breach.#1645: AirPlay iPhone to Mac for remote video, Siri learns to restart iPhones, Apple's Q1 2023 financials.1646: Security-focused OS updates, Photos Workbench review, Mastodon client wishlist, Apple-related conferences.1647: Focus-caused notification issues, site-specific browser examples, virtualizing Windows on M-series Macs.I highly recommend iDefrag for power users who may find the extra functionality indispensable as well as people that use their system for mission critical tasks or things like hard drive hungry video editing. iDefrag features an intuitive interface, plenty of options and a disk compaction mode, great for squeezing the last bit of space on that hard drive. I absolutely overestimated how much OS X attempts your drive healthy mine was completely fragmented. Another interesting feature in Layout mode is that you can click on a section of blocks and select View » Show Info Panel to find out what file or system resource you are looking at. The first, called Layout, shows a visual interpretation of the fragmentation on your hard drive while Statistics and Files just tell it like it is. When defragging your hard drive you are given three main ways to monitor things. The way that it works, your drive must be unmounted to perform more complex defrags although a simpler, on-line defrag option exists. IDefrag comes bundled with an application called CDMaker that can create a boot cd used to fully defrag your main OS drive. iDefrag offers so many options when it comes to defragging, kind of like what Diskeeper offers for Windows. I took a chance and purchased the full iDefrag for 30, a little steep for an app that just does one thing. The demo version of iDefrag is crippleware, only letting you defrag 100MB or less drives. I had spent some time and read about other competitors for Mac defrag applications but iDefrag made the most sense. ![]() I decided to check out iDefrag from Coriolis Systems after having heard about it last night on the Typical Mac User podcast (where Amber Mac happened to mention my 10 Things Every New Mac Owner Should Know article). Technically, OS X is supposed to take care of everything with a journaled filesystem and system maintenance when the computer is idle, but my system has become awfully slow recently. ![]() Today I explore the whole "You don't need to defrag" situation regarding Macs. ![]()
