MacBook Air M5 and fl studio lagginess

I recently bought a MacBook Air m5 with 32 GB of ram. I use Fl Studio 2026 for music production and the laptop is having some issues with running it smooth. The playhead after a few minutes of usage starts to lag and I used only one vst(analog lab v). Also the vsts which I use all support apple silicon according to their website. I have tweaked all the settings in the application but still nothing changed. I even switched the laptop for a new one and still an issues is here.

If anyone has any insight to this problem please help.

Playhead lag in FL Studio on a MacBook Air M5 is a known issue affecting MacBook Air users


Why It Happens

  • Passive Cooling / Thermal Throttling: The MacBook Air has a fanless (passively cooled) design. When a heavy, real-time plugin like Analog Lab V runs, the chip heats up quickly, throttles its clock speed, and causes audio underruns or playhead stuttering.

Try this

  • Open Activity Monitor (Applications > Utilities) while the lag starts to see if another process (like macOS indexing via mds_stores, cloud sync, or browser tabs) is spiking your CPU alongside FL Studio.
  • Because the MacBook Air lacks a fan, try propping the bottom of the laptop on a hard, elevated surface (or use a simple laptop stand) to improve passive heat dissipation. 


If the Mac is not becoming hot, please see this

  • Increase Buffer Length: Go to Audio Settings and raise the buffer length from default levels to 512 samples or 1024 samples (this increases latency slightly, which is fine for mixing/playback, and stops stuttering).
  • Set Priority to Highest: In Audio Settings, make sure Priority is set to Highest so macOS dedicates real-time core scheduling to FL Studio.
  • Lower Mixer Resampling Quality: Set the mixer resampling quality down (e.g., to 16-point sync). 

Optimize Plugin & CPU Setting

  • Enable Smart Disable: Go to Tools > Macros > Smart disable for all plugins. This turns off plugin processing when they are idle.
  • Enable Multithreading: Ensure Multithreaded generator processing and Multithreaded mixer processing are enabled in the Audio Settings.
