High Sierra: Cisco AnyConnect cannot be installed on latest MacOS 10.13.6 update due to inability to create / opt / directory at root

I have been using Cisco AnyConnect through my institution to connect to my work VPN.

However, I have been experiencing problems lately. I can't even start or reinstall Cisco AnyConnect on MacOS 10.3.6 (latest update)

I have tried debugging it on my own. I have made some progress to point out the problem. I will try to summarize it below:

  • Cisco AnyConnect tries to install files on the root below /opt/cisco (whereas on Mac OS the appropriate folder seems to be /usr/local/opt/...) This is the case in all versions of AnyConnect that I tested (4.5; 4.6 and 4.8). This no longer seems to be allowed in the latest version of macOS 10.13.6, hence failed installation (see points below).

  • Looking back on my TimeMachine, I had that /opt/ folder in the root until December 12 (date of the last update of macOS High Sierra). It actually contained only the Cisco files (proof that something unusual is in progress).

  • Since that macOS update in December, the /opt the folder at the root no longer exists (just /usr/local/opt) It is not allowed to create that /opt directory either. I tried but with no luck, even with administrator rights, root user profile and disabling & # 39; System Integrity Protection & # 39 ;. This happens using the GUI and the terminal (sudo mkdir /opt) The error messages are not useful (error 43 in the GUI and message "no such file or directory" exists in the terminal). I can create a new folder in the root, as long as it is not called "opt" (if I try to name it) opt I get error messages).

  • The last thing, I also tried to create /opt as a symlink to /usr/local/opt. There is no possibility there either.

If you have any ideas on how to proceed then it would be great! Thank you very much for your help (I tried to contact Cisco support but it seems you need to be the direct physical client to do so …).

Why does the cursor on my Macbook Pro 10.13.6 not respond when I click?

The cursor on my MacBook Pro does not respond when clicked. The cursor appears on the screen and I can double click, so I think it's a software problem. When I try to restart, it works for a minute but then stops working.

What version of Xcode should I download for high sierra 10.13.6?

which version of Xcode should I download for Mac high sierra 10.13.6, please note that I downloaded xcode 10.2 but it informs me that it requires Mac OS 10.14.3 or later.

grc inside terminal (with different colors in the terminal depending on the size of the files) does not work in 10.14.6 Mojave and works in High Sierra 10.13.6

I can put the tool to work grc which allows to have colors for permissions and different colors depending on the size of the files listed, for example, with ls -l I send.

In my previous MacBook with High Sierra 10.13.6, I show you an example of what I get:

grc working

As you can see, I have a color code for different file sizes (increasingly white, yellow, green and red).

Now, on my new MacBook with Mojave 10.14.6, with the same ~/.bashrc Y ~/.bash_profile files, I can't have the same representation as for the High Sierra 10.13.6 MacBook pro. Here below what I get:

grc does not work

You can see that no colors appear for size files (unlike the High Sierra case).

I get the same problem when I do a ssh from Mojave to High Sierra.

Here the content of ~/.bashrc In the Mojave version that does not work:

############ dircolors binary #################
export PATH=/opt/local/libexec/gnubin:$PATH 
###############################################

export CLICOLOR=1
export LS_COLORS='README*=4;31:*.txt=1;35'

########### alias l #######################
alias l='grc -es --colour=auto ls --color -G -lrt'

by ~/.grc/grc_bash, I have put :

At first glance, where could the error come from? Maybe I forgot an environment variable or an unsupported option for ls -lrt that would avoid the color code for the size of the files …

Any comments are welcome, Regards

macbook – Download Xcode 10.2.1 in macOS High Sierra (10.13.6)

I use MacBook pro with macOS High Sierra (10.13.6). The version of Xcode that I am using is 10.1 and I see that the updated Xcode in AppStore is 10.3, which is not compatible with my environment since I expect macOS Mojave 10.14.6.

How can I get Xcode 10.2.1 that was released after the release of Xcode 10.1? Will MacBook Pro with macOS High Sierra (10.13.6) also receive the macOS Mojave 10.14.6 update? Thank you

Update – High Sierra 10.13.6 – Security Update 2019-003 Installation Failure

My 15 "MacBook Pro (Retina, mid-2012) is running slowly since I tried to install Security Update 2019-003 High Sierra 2019-003 After investigating the problem, I discovered a series of reports indicating that the update I had failed other users and decided quickly I will wait for Apple to launch an "updated" update, however, since the failed installation attempt, my machine is running so slowly that I can hardly use it. "Something as simple as moving A document in a different folder stops the machine, like the opening of a website, I tried to restart it in vain and test the speed of my IP, I know enough about my Mac to realize I know very little and I'm terrified to start opening folders and deleting things without the advice of someone who knows what to do. Now that I have revealed that I am a complete computer dodo So, I hope not to be embarrassed anymore. History: I received an automatic update from the App Store that a restart was required for security update 2019-003. However, when I clicked on restart, my MacBook Pro changed to a black screen with just the cursor on the screen. The next morning nothing had happened and the only option I had was to make a hard shutdown and restart. When I saw that the update had not been installed, I continued after making space on my disk. After several unsuccessful attempts, I found information that the update had failed other users with the same circumstances that I encountered. My problem is that I do not know how to delete the part of the update that is there and ready to install, which I think makes my machine run so slowly. I have searched many times and ways, but I can not find anything about how to remove what was downloaded and pending installation after the restart. Does anyone know where I can locate this on my Mac and how can I rid it of my life? The update is obviously flawed and I just want it to be removed from my machine. Any help is appreciated. Sincerely, Kathryn

Network – WOL with an iMac (10.13.6)

I could not configure WOL (Wake on Lane) from my iMac run-on 10.16.6.

  1. I have Wake for access to the network enabled from the system preference / Energy Saver

  2. I entered the MAC ethernet (and not the airport)

I have this configuration in my router (Synology RT1900AC), when I manually turn on my iMac, the router detects and there is a lighting cable next to the MAC address (but I guess maybe only because the network detects some packet of this MAC … )

Is there anything else I need to do to make WOL work?

mac appstore – macOS High Sierra (10.13.6) Updates can not be installed

I have difficulty installing the latest update on my Mac Mini since 2001 (macmini5.3).

The current pending update is "Security Update 2019-003-10.13.6". When I try to install the update:

  • Download the update
  • Restart is requested.
  • You get ~ 5% through a progress bar and then an error message appears: The update was not installed correctly. You can try updating again in the App Store after restarting.

I have tried in order:

  • Manual download and installation of the update.
  • Solve disk problems in repair mode (not found).
  • Installing the update in Safe Mode.
  • Installation of the update in repair mode.
  • Reinstalling macOS.
  • All the above again, with a support technology in the chat.

The problem that triggered the triage wave is that Dropbox must be updated manually by downloading a new version. The download is delivered in .dmg format. It turns out that in this state, the operating system can not open a .dmg file and fails to "separate it because there are no mountable file systems". This same message is displayed for both the Dropbox updates and the Apple system update (SecUpd2019-003HighSierra.dmg).

I "feel" (hahaha, there is no data to support this) as the format for the .dmg file has changed. And Apple could not release an update of this version of macos, so the format is no longer readable.
