Choose Another Startup Disk with the Startup ManagerTo boot from a specific device, press and hold the Option key while booting your Mac. You’ll see the Startup Manager appear. From here, you can choose to boot from different connected hard drives, USB flash drives, network locations, and other boot devices.To skip the Startup Manager and boot straight from a removable device—for example, a CD, DVD, or USB drive—instead of its internal drive, press and hold C. To boot directly from the network with Netbook, press and hold N instead.Test Your Hardware with Apple DiagnosticsApple Diagnostics tests your Mac’s hardware to ensure it’s working properly. On Macs released before June 2013, Apple Hardware Test (AHT) will appear instead of Apple Diagnostics.To access this tool, press and hold the D key while booting your Mac. Select your language and your Mac will automatically test its hardware and inform you if anything is wrong. Load the Bare Necessities with Safe ModeMacs offer a Safe Mode, also known as Safe Boot.
When you boot in Safe Mode, your Mac will check its startup volume, only load necessary kernel extensions, and disable third-party fonts and startup options. It’s like —it won’t load third-party hardware drivers or startup programs, so you can use this mode to fix problems if your Mac isn’t working or booting properly.To load your Mac in Safe Mode, press and hold the Shift key while it boots. You can stop holding the Shift key when you see an Apple logo and progress bar. To leave Safe Mode, just reboot your Mac without holding the Shift key.Troubleshoot from the Command Line with Single-User ModeIn single-user mode, you’ll be presented with a text-mode terminal you can use to enter commands you might need to troubleshoot problems.
These Safe Finder removal instructions work for Safari, Chrome and Firefox, as well as every version of Mac OS. Safe Finder is a potentially unwanted application aimed at promoting fake web search engines. It would typically infiltrate a user’s system without the user’s knowledge or consent. Download Malwarebytes for Mac (the free version) and you get a 14-day trial of the premium version with automatic (real-time) virus and malware protection. After 14 days, your trial reverts to a limited disinfection scanner. Buy the premium version now to prevent infection in the first place.
This works like —rather than getting multi-user operating system, you boot directly to a root shell.Press Command+S as your Mac boots to enter single-user mode. To leave this mode, type reboot at the prompt and press Enter.See More Detailed Information with Verbose ModeIn verbose mode, you’ll see normally hidden messages appear on your screen. If your Mac is freezing, especially during the boot process, the messages here can help you identify and get help with the problem.Press Command+V as your Mac boots to enter verbose mode. You’ll see the terminal messages appear during the startup process. If everything goes properly, your Mac will boot to its normal desktop.Get Other Tools (or Reinstall macOS) with Recovery ModeRELATED:Recovery Mode provides various graphical tools for working with your Mac. From here, you can, restore your computer from a Time Machine backup, or use the Disk Utility to repair, wipe, and partition your Mac’s internal disks.Press Command+R as your Mac boots to access Recovery Mode. If necessary, you’ll be asked to connect to a network so your Mac can download the appropriate recovery software.
You can then choose your language and use the graphical tools here.One of the nice things about a Mac is that this is all built-in. You don’t even have to download a macOS installer to access these tools—if necessary, your Mac will download the macOS installation files for you when you choose to reinstall the operating system. Better yet, it will download the most recent version of macOS so you won’t have to spend hours installing patches and service packs, as you do on Windows.
What is FUSE for macOS?FUSE for macOS allows you to extend macOS's native file handling capabilities via third-party file systems. It is a successor to, which has been used as a software building block by dozens of products, but is no longer being maintained.FeaturesAs a user, installing the FUSE for macOS software package will let you use any third-party FUSE file system. Legacy MacFUSE file systems are supported through the optional MacFUSE compatibility layer.As a developer, you can use the FUSE SDK to write numerous types of new file systems as regular user space programs.
The content of these file systems can come from anywhere: from the local disk, from across the network, from memory, or any other combination of sources. Writing a file system using FUSE is orders of magnitude easier and quicker than the traditional approach of writing in-kernel file systems. Since FUSE file systems are regular applications (as opposed to kernel extensions), you have just as much flexibility and choice in programming tools, debuggers, and libraries as you have if you were developing standard macOS applications.How It WorksIn more technical terms, FUSE implements a mechanism that makes it possible to implement a fully functional file system in a user-space program on macOS.
It provides multiple APIs, one of which is a superset of the (file system in user space) that originated on Linux. Therefore, many existing FUSE file systems become readily usable on macOS.The FUSE for macOS software consists of a kernel extension and various user space libraries and tools. It comes with C-based and Objective-C-based SDKs. If you prefer another language (say, Python or Java), you should be able to create file systems in those languages after you install the relevant language bindings yourself.The repository contains source code for several exciting and useful file systems for you to browse, compile, and build upon, such as sshfs, procfs, AccessibilityFS, GrabFS, LoopbackFS, SpotlightFS, and YouTubeFS.
