Basic content

The first step is to use cleanmymac to uninstall the original switchresx and csrutil disable to close sip, which is not described in detail here

The second step is to download the latest switchresx 4.6 and install it for all users on the computer

Part 3: create a new administrator role, such as Wang Ergou

Part 4: log off the current user, enter the new user shadow, open switchresx, and then create a new customer resolution, such as scale 3840×2160 (1080 hidp), according to the steps in the figure below. After that, you will be required to enter the password, and then restart it to find that it is effective

Step 5: enable sip, enter the original account and delete the new shadow account. It’s over. It’s perfect~
