RDP on MacBook Pro (Silicon) using over 3GB of memory.
Hi,
New macbook pro m4 pro and having only one RDP connection opened, but for 3days, RDM is using 3.5GB of ram. Connection is opened to a LAN PC, and not even focused on the tab (using it for OTP codes mostly).
Closing the RDP session does not free up the ram.
(also, a bunch of about: processes that exits if application is closed)
Version: 2025.3.6.9
Thank you.

Hello,
Thank you for reaching out to us regarding this matter.
Could you please confirm the type of RDP in use? For example, is it FreeRDP?
In the meantime, could you also check if there is any device or system currently enabled or associated with this entry?
Best regards,
Tommy Sanders

Hi, using it only in tabbed/embedded mode - If I was to using it detached, I have the Microsoft app for that so not sure who would use RDM to open sessions same as you do with the MS app :)
Hello,
Thank you for your response.
I will run some tests tomorrow and will follow up with you shortly afterward.

Hi, just an update - now on 2025.3.9.2 - no change, leaving the app opened for 1-2 days and it still grows over 3GB :(
Since the last report, ram is now more expensive than gold :)

Here’s how to show “Real Memory” in that view (macOS Activity Monitor style list):
- Open the window with the process list (where you see Process Name / Memory / Threads / Ports).
- Move your mouse to the column header row (the bar that says Process Name, Memory, etc.).
- Right-click (or Control-click) directly on that header row.
- In the menu that pops up, find and check “Real Memory”.
I'm whatever Gotham needs me to be.

Hello @iustinn
Thank you for your patience.
Could you please let me know whether RDM, when idle after a reboot, shows the same level of resource usage? Additionally, can you confirm whether you had multiple sessions open before reviewing the Activity Monitor?
Could you also please confirm the following:
The specifications of your machine
Your typical usage pattern with RDM (for example: the types of sessions you mainly use, whether you have many long-lived sessions, frequently open and close sessions, or typically keep the application running for extended periods)
I look forward to your reply.
Best regards,
Tommy Sanders
