Mac Os X Remote Disk Just Appeared 2017

Lot of Mac OS X users reported this issue in Apple support communities. External hard drive showing up in Disk utility not in Devices. This problem also happened after OS X Yosemite update.

Having to play around with large video files can be a headache when my system has a blazingly fast SSD drive but is only 500GB in size. Going to the macOS storage analyzer can be a mixed bag of easy to understand actions to reduce disk usage to cryptic descriptions that are more daunting to deal with.

We have spoken about how to rid your computer from data noted in 'other' which in short is space taken up by caches, plug-ins, and documents. But now we'll show you how to reclaim some of your disk space from your 'System' disk usage.

Time Machine and local backups

If you run Time Machine for backups over Wi-Fi like I do, then macOS High Sierra will simultaneous use your remote backup disk and your local disk to save backups to. The reasoning behind this is that in the event the remote backup disk is not available or present, then you can recover files in spite of a missing remote backup disk and recover from the local disk.

In fact, macOS High Sierra manages this disk usage seamlessly without user intervention. It also purges local backups if disk space starts to get too low. However, sometimes the purging doesn't happen to leave enough disk storage for my very large video files and I'll get a 'not enough disk space' message. And instead of waiting for macOS to catch up with my disk space requirements, I can force the purging from the terminal.

Determining if you have a large amount of 'System' disk usage

To see if this method will help you reclaim some disk space we need to check the macOS System Information.

  1. Click the from your desktop.
  2. Click About This Mac.
  3. Click the Storage tab. You'll be greeted with a color-coded categorization of what your disk is being used for.

In my case, 'System' (meaning the operating system) was clearly using the most space. Although I understand the reasoning behind why Time Machine is storing local backups, I didn't feel that I needed so much of my disk space devoted to these local backup snapshots.

If you have other categories that have very high disk usage you can click the manage button to get more details on what is using that disk space and possibly delete those things that you determine to no longer have use for.

Purging local backups

Please note that although this doesn't affect your remote backup from Time Machine, this will get rid of the redundancy (at least until the next Time Machine backup) that a local backup disk will provide. If you need such redundancy or are worried about the recovery of your data then you would be best served to let macOS determine when to purge these files.

  1. Start Terminal from spotlight.
  2. At the terminal type tmutil listlocalsnapshotdates.
  3. Hit enter.

Here, you'll now see a list of all of the locally stored Time Machine backup snapshots stored on your disk.

Next you can remove the snapshots based on their date. I prefer to delete them one at at time. Once my 'System' disk usage is at an acceptable level, I stop deleting but you can delete all of them if you want to reclaim all of the disk space.

  1. Back at the terminal, type tmutil deletelocalsnapshots where will be one of the dates from your backup. This will be in the form of xxx-yy-zz-abcdef. Try to start with the oldest snapshot.
  2. Hit enter.
  3. Repeat for as many snapshot dates as required.

You can watch your System Information graphic free up disk space in real time to see if you've removed enough.

I want to stress that this should only likely be used if you absolutely immediately need to reclaim the disk space. Otherwise macOS does a pretty good job in managing the unused disk space for local backups and purging when it deems necessary.

Are you running out of disk space? What have you done about it? Let us know in the comments!

When their specialist kit failed, soldiers turned to an iPhone to get the job done.

Update 11/29/2017 9:47 AM California time: Apple patched the flaw on Wednesday morning. Installing the patch immediately is the best way for Mac users to protect themselves and supersedes any mitigation advice. What follows is the story as written before the patch was available.

In one of Apple's biggest security blunders in years, a bug in macOS High Sierra allows untrusted users to gain unfettered administrative control without any password.

The bypass works by putting the word 'root' (without the quotes) in the user name field of a login window, moving the cursor into the password field, and then hitting enter button with the password field empty. With that—after a few tries in some cases—the latest version of Apple's operating system logs the user in with root privileges. Ars reporters were able to replicate the behavior multiple times on three Macs. The flaw isn't present on previous macOS versions.

Hola, buenas tareds para todos.

Hay mucho software pare Mac OS X, eso es innegable y quien diga lo contrario miente rotundamente, los programas para acceder a Base de Datos y poder ejecutar consultas SQL sobre ellas no son una.

The password bypass can be exploited in a variety of ways, depending on the way the targeted Mac has been set up. When full-disk encryption is turned off, an untrusted user can turn on a Mac that's fully powered down and log in as root. Exploiting the vulnerability was also not possible when a Mac was turned on and the screen was password protected. Even on Macs that have filevault turned on, the bypass can also be used to make unauthorized changes to the Mac System Preferences (including disabling filevault), or the bypass can be used to log in as root after logging out of an existing account but not turning off the machine. The behavior observed in Ars tests and reported on social media was extremely inconsistent, so results are likely to vary widely.

The upshot of all of this: as long as someone has filevault turned on, their files are most likely safe from this exploit as long as their Mac is turned off before an attacker gets hold of it. Locking a screen with a password also appeared to protect a computer while it's unattended.

Privilege escalation

Of more concern is that malicious hackers can exploit this vulnerability to give their malware unfettered control over the computer and OS. Such escalation-of-privilege exploits have become increasingly valuable over the past decade as a way to defeat modern OS defenses. A key protection found in virtually all OSes is to restrict the privileges given to running software. As a result, even when attackers succeed in executing malicious code, they're unable to get the malware permanently installed or to access sensitive parts of the OS.

'This looks like something that a piece of malware or an attacker could use in a multistage attack,' Patrick Wardle, a researcher with security firm Synack, told Ars. In cases such as these, attackers use one exploit to run their malicious code and a second exploit to escalate the privileges of that code so it can perform actions that the OS normally wouldn't allow. 'This appears to be one way malware or an attacker would be able to do that.'

Amit Serper, principal security researcher at Cybereason, said his tests showed the vulnerability is located in com.apple.loginwindow, a macOS component that's one of at least two ways users can log into accounts. He said he was unable to reproduce the exploit using a Mac's terminal window, although he said he saw reports on Twitter from other people who said the bypass worked using the terminal window as well. Whatever the case, he agreed with Wardle that the flaw likely represents a major privilege-escalation vulnerability that can be exploited easily by malware developers.

'If they're using API (programming interface) calls, it's a matter of writing the appropriate code,' Serper told Ars. 'An attacker should be able to trigger it.'

The vulnerability can also have dire consequences for people who have made their Macs accessible through remote management screen sharing provided through macOS or third-party services. Will Dormann, a vulerability analyst at CERT, said on Twitter that having remote options turned on will allow attackers to remotely access the machine with no password required. Results from a quick search that were posted on Twitter showed more than 105,000 Macs alone had the VNC remote desktop app installed. To check if remote management or screen sharing is on, users can check the Sharing menu in System Preferences.

The bug came to light Tuesday morning when a Mac user contacted Apple support representatives over Twitter:

Dear @AppleSupport, 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. Are you aware of it @Apple?

Remember goto fail?

A vulnerability that logs users in as root without requiring any password at all is extraordinary, both because of the lack of testing it suggests on the part of Apple developers and the potential harm it presents to end users. The last time in recent memory Apple made an error of this magnitude was the so-called goto fail bug that gave attackers an easy way to bypass TLS encryption. It took Apple four days to patch the critical flaw, which got its name from one of the lines of code responsible for the vulnerability.

Apple representatives issued the following statement:

We are working on a software update to address this issue. In the meantime, setting a root password prevents unauthorized access to your Mac. To enable the Root User and set a password, please follow the instructions here: https://support.apple.com/en-us/HT204012. If a Root User is already enabled, to ensure a blank password is not set, please follow the instructions from the 'Change the root password' section.

Specifically, users should do the following:

  • open the Users & Account menu in System Prefereces
  • click the padlock at the bottom and enter an administrator name and password
  • click Login Options
  • Click Join (or Edit)
  • Click Open Directory Utility
  • Click the padlock at the bottom and enter an administrator name and password
  • From the menu bar in Directory Utility, choose Edit > Change password
  • Enter a strong password

The most important part for now is not to disable the root account. That only allows the root account to be re-enabled by putting 'root' in a user name field and leaving the password blank. Until Apple issues a patch, people should secure the root account with a strong password and leave the account enabled. As always, passwords should be at least 13 characters long, randomly generated, and contain a mixture of numbers, upper- and lower-case letters, and symbols. As an added layer of security, users should also ensure they have filevault turned on.

Some researchers are speculating unsecured root account doesn't exist until someone with physical access to the Mac attempts to log in while leaving the password blank. That has prompted advice Mac users not test their systems lest they create a persistent root user account that wasn't there previously. Other researchers report here and here being able to exploit the weakness to remotely log into a Mac, with no previous local login attempts.
