High Sierra Security Bug Found
As noted in a tweet by Lemi Orhan Ergin in November of 2017, there apparently is a big security issue in the Users and Groups area of Mac OS X High Sierra (it doesn’t appear to happen in earlier versions of Mac OS X).
Here’s the gist of the problem that Lemi Orhan Ergin found:
“We noticed a *HUGE* security issue at MacOS High Sierra. Anyone can login as “root” with empty password after clicking on login button several times.”
Fortunately, there is an easy fix until this gets patched (which may have already happened in the upcoming Mac OS X 10.13.2 beta). The fix is to assign a strong password to the built-in root account by following the instructions given by Apple here. In essence, you have to perform the following steps:
- Choose Apple menu () > System Preferences, then click Users & Groups (or Accounts).
- Click , then enter an administrator name and password.
- Click Login Options.
- Click Join (or Edit).
- Click Open Directory Utility.
- Click in the Directory Utility window, then enter an administrator name and password.
- From the menu bar in Directory Utility:
- Choose Edit > Enable Root User, then enter the password that you want to use for the root user.
You can also set a password with the Terminal by typing in ‘sudo passwd -u root’ and hitting return.
I had a vexing issue the last few days with 1 of 3 external monitors on Mac OS X 10.11.6, where this one display would not wake up after the computer or display went to sleep. I switched around the monitors, unplugged and replugged them, and nothing seemed to help. I went to the point of disconnecting the monitor and replacing it with another extra display. This worked–to a point. Then, it happened all over again. I thought it was the port on the video card, since this is a Mac Pro with 2 cards. Eventually, any monitor plugged into this port would not wake back up after sleep.
Low and behold, I found a fast and easy solution–since it’s only been one time since the monitor has done this since I found the new trick, I can’t say for sure if it’s still a software issue, or a hardware issue, however, this trick worked to get the monitor lit up without unplugging or restarting:
1.) Go to System Preferences –> Displays
2.) Hold down the Option key and click on the “Gather Windows” button
3.) Click on “Detect Displays”
At this point, the sleeping monitor should wake right up!
Now, Apple–You know this isn’t right. You’re about to alienate a whole lot of people with this latest nonsense (remember the #applescript thing this week?) They all bought your phone and it’s clearly broken–it’s not their fault so don’t charge them for something that they didn’t cause, didn’t build or have any control over. Do the right thing and fix your phone on your dime. Sign this petition to help show Apple that these kinds of tactics are not right. #apple #iphone
I personally rely on a myriad of scripts to automate routine functions at my job as a graphic designer and would be lost without these time-saving scripts.
Only Apple can decide to make this technology stay in the operating system and I hope that you will sign and share this with anyone you know who relies on Applescript and scripting technologies on Mac OS X.
Apple has decided to remove the Macintosh boot chime (or f-major tone) that has been a staple of the Macintosh since 1998. Apple also removed quite a few of the other iconic features that has made the Mac identifiable including USB ports, the glowing Apple logo and physical function keys, which were replaced by the fancy new Touch Bar.
To reenable the iconic MacBook startup chime, head to the Terminal, located in the Applications —> Utilities folder and type in this line (and then enter in your admin password):
sudo nvram BootAudio=%01
Hit return and you should now hear the tone at every startup. To turn it off, type in this line:
sudo nvram BootAudio=%00
