I have a MacBook Pro (2018, 13-inch) with Catalina.
Every once in a while, my mac gets weird. All the tabs open on Chrome go black and if I try to reload, the whole app usually just quits. Other apps freeze as well. My open Word documents also suddenly get different file names (like .W89712 or something) and get saved to a strange different folder (com.microsoft.Word).
Is this just a memory problem? I feel like I don't run anything crazy on my computer. Mostly just Chrome, Word (1-2 documents), Acrobat (1-2 documents) and the Mail app.
