macOS Sequoia Massive memory leak

I found the Reason！

When the mouse passes over the top window special effect every time, Windowser would be larger and larger and won't be erased.

THIS NEEDS TO BE FIXED IMMEDIATELY!

The speed at which it gets fixed is directly related to how much information you provide Apple and the number of people who report it to Apple.

Note: Apple isn't here.

My MacBook Air is now virtually unusable, since "upgrading" to Sequoia 15.1.1. Out of memory about every 5-10 minutes. Rebooting 3-4x per hour. Closing apps doesn't seem to help.

Review the processes you have launching on startup. The easiest way is to use EtreCheck.

If you use Google Chrome, be aware that it is a memory hog and that is compounded with multiple tabs.

Me too.

Since updating to Sequoia, after opening iPhone Mirroring, the ram of windowserver will become larger and larger and it won't be erased when I close all the apps.

(M1 Pro/16G)

I too have the memory leak issue.

Also, the screen flickers intermittently without apparent reason.

Kindly hope a fix is in the works ahead of macOS 15.1 release next month.

I have the same problem. it keeps getting bigger and bigger over time. especially when i use iphone mirroring it keeps adding around 500 mb every time i open it.

It's also important to remember that modern operating systems are specifically designed to use the available RAM. Unused RAM is wasted RAM. What do you see when you look at Memory Pressure? If it's green (or even occasionally yellow), you're fine.

I run dual displays, have a ton of App's open, haven't restarted in days and like Barney, I'm not seeing a memory leak.

To get a better look at what might be ailing your system,

Download and run the free version of EtreCheckPro, from > https://etrecheck.com/en/index.html

Then post the Report, as per > How to use the Add Text Feature When Post… - Apple Community

Post the free EtreCheck report using the Additional Text option when posting. It contains no personal information and will provide more information about what is going on with your System.

Sounds like you have a third party process or malware related to crypto mining software that may have been attached to an application you downloaded.If you download torrents, that is the source. As stated many times in this thread, the way to determine that is by posting the free EtreCheck report. It is likely that the same problem will come back the next time you reboot your computer.

I just submitted a detailed support ticket to Apple. Hopefully something will be found

A lot of the posters here seem to regard increased RAM usage as a problem in itself when the only problem is when there is not enough RAM and a programme has to be closed or, worst case, a new machine purchased.

No offense, but I’m using 2021 m1max with 64gb ram and 2t storage.

And windowserver process takes 13+gb memory after I quit all applications and services. When I put it away for one night, no memory was released. Also, no external display connected.

Before posting here, I’ve done several experiments and identify this issue is associated with iPhone mirroring.

As you can see from cytan in this thread, their case was caused by a third party process that was launching on startup and once removed by using the suggested tools, the problem went away. You have not identified the cause to your problem, you have seen what happens when the third party add-ons in your System folders conflict with the OS.
