After a while, arsenic the fig of progressive processes and inheritance apps increases, the baseline Macs commencement lagging, an contented I've encountered respective times connected my M1 MacBook Air (8GB). To code this, see closing resource-heavy processes and apps that are moving successful the background.
Sometimes, erstwhile you deliberation you've closed an app, it keeps moving successful the inheritance (denoted by the dot beneath the app's icon successful the Dock). In this case, you tin right-click the app's icon and prime "Quit" from the discourse menu.
