It’s not sure whether it’s the system or the M1 chip. The PC version client can’t log in. After the IOS / iPad version logs in, it can’t access the VPN intranet. After a long tour, I saw the open source third-party solution on GitHub, https://github.com/adrienverge/openfortivpn , run after installation

brew updateThere are many ways to display hidden files in MAC,
1. Terminal
The simplest is to enter commands on the MAC terminal.
Show hidden files (note space and case):
defaults write com.apple.finder AppleShowAllFiles -bool true
or
defaults write com.apple.finder AppleShowAllFiles YES
Do not show hidden files:
defaults write com.apple.finder AppleShowAllFiles -bool false
or
defaults write com.apple.finder AppleShowAllFiles NO
After input, click enter, then exit the terminal directly and restart finder.
Restart the finder: first force to exit the finder, and then restart the finder.
2. Shortcut key
MacBook Air command not found. This may have been caused by modifying the Profile when configuring Java Path.
: ls CD, vim, sudo, man command not found
1. First, enter commands so that you can use commands such as Vim temporarily
export PATH=/usr/bin:/usr/sbin:/bin:/sbin:/usr/X11R6/bin
Then open ~/.bash_profile
vim ~/.bash_profile
2. Add PATH
export PATH="/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:${JAVA_HOME}:${JAVA_HOME}/bin"
3. Restart Profile
source ~/.bash_profile
Exit Terminal, open it again, and type Vim to see if it works
input in terminal brew install wget if it is found that the brew didn't hold so first installation brewbrew installation method: ruby - e "$(curl - fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

zsh: command not found: rename
So use Homebrew to install it first:
➜ ~ brew install rename
After that, you can directly use a simple one-line command to change the name of multiple files. The general format is as follows:
➜ ~ rename 's/old/new/' *.files
Ex. :
Change the prefix of batch PNG files from ‘ic_’ to ‘ic_setting_’ :
(ic_launcher.png -> ic_setting_launcher.png)
➜ ~ rename 's/ic_/ic_setting_/' *.png
Modify part names of batch files:
(ic_setting_launcher.png -> ic_launcher.png)
➜ ~ rename 's/_setting//' *.png
Supplement:
You can also use :
to change the first five letters to XXXXX (note ^… It’s five.
for i in `ls`; do mv -f $i `echo $i | sed 's/^...../xxxxx/'`; done
Usage is almost the same, the rest is up to us to flexibly use.

Take the PNG file for example
1. Open the terminal
cd to the specified folder
3> The input
for i in *.png;do mv "$i" "${i%.png}@2x.png" ;doneYou can do what you want
ICloud Drive is a very useful feature that makes it easy to share files and documents between your devices (including other Macs, iPhones, and iPads) by automatically synchronizing and copying files between devices, so you should only disable iCloud Drive if you don’t have it enabled. So how to disable the iCloud drive on the Mac, there is a need for friends to welcome the reference!
Please note that this is disabling iCloud Drive completely on the Mac, not just disabling the iCloud desktop and documents that only store these two directories in iCloud.
Before attempting this step, make sure your Mac has a valid Internet connection.
The specific methods are as follows
1. Go to the Apple icon in the menu bar and select “System Preferences”.
2. Select “iCloud Settings”.
3. Uncheck the iCloud drive next to this check box.
4. Make sure to disable the iCloud drive and remove the iCloud files from your Mac.
You now have two options to choose what you want to do with your iCloud file.
Keep a copy – This keeps a downloaded copy of the iCloud files on the Mac. This option is recommended if you want to access the files offline later. This option works for most Mac users.
Delete from Mac – Selecting this option will remove all files from the iCloud drive on your Mac, and you will no longer be able to access these files on your computer.
5. Once you have selected the desired options, exit System Preferences on your Mac.
When you close the iCloud drive on your Mac, you’ll notice that the iCloud options disappear from the sidebar of the Finder, as well as from the Dock or anywhere else on your system. This is because you have completely disabled iCloud Drive from your Mac. You will not be able to save, copy, move, or upload files from your Mac on your iCloud drive.
To re-enable iCloud Drive, go back to System Preferences and select the iCloud Drive box.
