On startup hold Command+Option+R. You can now use Internet Recovery to install OS X. Don't download from shady sites. You are compromising your security this way.

Restarting your machine won't damage it physically. The only damage that you can really do to your machine is to the software and/or firmware. The only way that restarting can do that type of damage is if you restart while operations are still active (i.e. an EFI update or disk activity). Other than that, you are pretty safe.

I had to download one for El Capitan from a shady website. Eeek. I would not trust that, personally. Do you have access to a good internet connection? If so, you can use OS X Internet Recovery to install a fresh version of Mac OS X via your internet connection, directly from Apple.

Use an Alias. The alias command allows the user to launch any command or group of commands (including options and filenames) by entering a single word alias rm="rm -i" The next time you issue the command rm it will issue rm -i You can also make a new alias in case you want to keep rm functioning as it does by default. To create a new alias alias ...

Security is best implemented as a Multi Layered, Multi Vectored Strategy. The Principle of Least Privilege (POLP) is just another cog in the machine that keeps your computer secure. Everything that you listed there are all good but none of that will prevent someone from taking over your computer with an exploit such as the Dropped Drive Hack. How does a ...

No. No battery will be saved regardless of what color your screen is. This only applies when the screen is OLED, like in the Apple Watch. You can save battery by lowering the screen brightness, though.

YES! You can either make a Genius Bar appointment or you can do a walk-in. If you do a walk-in for the genius bar you may have to wait a bit, but they will do it for free. The instillation may take a little while, so plan on having some free time and a good book (or movie or something - there's free in-store wifi). Each store typically has good internet and ...

As Tom Gewecke mentioned in a comment, Adobe Acrobat can do this. I was also able to do this with PDFpen, as also suggested by Tom Gewecke. Both apps seem great. Since both of them are quite pricey, though, I would also like to share a way to do this with the free and open source software LibreOffice. Open the PDF with LibreOffice. Click Edit in the ...

Just to clarify, the term Router is incorrect here (mostly because it is used incorrectly by manufacturers who sell products in the retail market). A router is neither compatible nor incompatible with Time Machine. A router routes network traffic (packets) from one network to another. What these "routers" actually are is an amalgamation of a network ...

Just tap the Tab key twice (TabTab). You'll be prompted if you want to see all possible commands. Tap y and you'll be presented with a list. You can do that same thing for individual commands to see all options for that specific command.

Cursors are rendered using CoreGraphics The Wait Cursor or what is sometimes affectionately know as the "spinning beachball of death" is rendered in CoreGraphics (Apple's 2D rendering engine). Meaning, they are generated on the fly depending on what your preferences are set to (i.e. cursor size). The CoreGraphics file is located at /System/Library/...

You could try using terminal. I suppose that you can not remove the files from external drive trash (Mac use separated trashed for each drive). In order to remove external drive files try this: Open Terminal Write: cd /Volumes/{Your External Drive Name}/.Trash Check that your files are there with: ls -la Remove them using: sudo rm -rf ./* It will ask ...

No, Windows offers different recovery features than OS X. Particularly Windows is creating automatic (and allowing manual creation of) system restore points. Restore points are created to allow users a choice of previous system states. Each restore point contains the necessary information needed to restore the system to the chosen state. Restore points ...

It's not possible to open folder with one click in default "Icons" view in Finder. However switching to "Columns" view (cmd-3) will allow you to open folder with one click. Also it could be faster to just use hotkeys instead of trackpad/mouse. Use arrows to navigate inside "Icons" view, cmd-down to open selected folder and enter to rename selected file or ...

There's basically two things you need to do to secure your Mac from a (involuntarily) separated employee: Secure from outside access Change all passwords This is an overlapping approach because neither are 100% foolproof. However, if you remove as many of the access paths from outside the organization, whatever is missed will be covered by the changed ...

It is generally considered best practice to use an account that has no more privileges than are required. What this means generally is that you should use an account that has the lowest privilege level possible, and elevate your privileges when it is needed for a specific task that requires the higher privileges. However, this gets annoying rather quickly. ...

Simple... Up arrow ↑ then continue.

A netsh counterpart for manipulating network settings would be the networksetup command, but to achieve what you want, the easiest would be to define two separate network locations in GUI, one with static IP, the other one with DHCP. Then execute: # scselect Defined sets include: (* == current set) 02080D27-B377-4942-BB3A-CF0C8F049F9E (static IP) * ...

There is no OS X El Capitan install disk. OS X is distributed through the App Store now. Yes, ask your friend to create a bootable installer for OS X El Capitan. It should be a fairly straightforward process. Once you have the drive, hold down the option key while restarting your Mac to boot from the installer USB.

You also need to set HISTSIZE=10000000. HISTFILESIZE determines the number of lines to keep in the history file while HISTSIZE determines the number of lines to keep in memory. Both default to 500 Execute echo $HISTFILESIZE $HISTSIZE before you make the change and then again after. You should see 10000000 500 first then 10000000 10000000 after.

yup! boot off of your installation usb drive and instead of going straight into the install run 'Disk Utility' and remove all your partitions.

Yes. That's how homebrew does. You can usually trust brew doctor to tell if things are correct - it is pretty good about flagging anything amiss in /usr/local. But to confirm your main question, the normal for homebrew it that it's noted for being "chatty" in that directory with many files and folders.

Open up your script in Script Editor. Do a Save As... (hold Option key down and "Duplicate" in File menu will change to "Save As..."). When you save your script as an application this time, make sure the box that says "Show Startup Screen" is not checked. See my screenshot. That's all there is to it. Your old script was saved with the "Show startup screen" ...

If you click Deny on the picture you posted, then no further notifications will be shown [& the connection will be denied] for gamed trying to connect to (static.gc.apple.com AND port 443), not for (static.gc.apple.com OR port 443).

This is because your iOS device supports the Exchange Active Sync (which is for mobile only) protocol where Mail and Calendar do not. For your OS X Mail and Calendar to work, you either need: Exchange protocol support in Mail and Calendar meaning Apple has to pay for licensing (not likely to happen) IMAP, CalDav, and/or POP3 service enabled on the ...

Drag the folder from the share to your desktop (Hold CMD and Alt). Then add that alias to the sidebar

Making the user input a tone used to be the default in OS X, but not since at least OS X 10.8. Now it continues to guess your characters as you keep typing, and since it's pretty good at guessing, I guess tone selection was deemed an unnecessary step. There may be some way you can fiddle with com.apple.inputmethod.SCIM.plist or com.apple.inputmethod.TCIM....

Hitting ESC to get rid of the autocorrect suggestion works for me.

I figured it out myself, so I'm posting the answer in case anyone else has this problem. The answer was that gromacs has changed since the version I used most recently, and the commands I was used to no longer exist. For example, the g_energy command now runs as gmx energy. If you are also having this problem, gmx help commands should give you a list of ...
