This morning while using my late 2012 iMac I noticed that a lot of folders on my external drive had a modification date of 8/3/18. I knew just by looking at them that there was no possible way that they should have that date since they had all been on the drive much longer than two days, and I had not made any modifications to them. When I started examining the contents of these folders, the modification date suddenly changed to today, and the modification time changed to the current time. I ran a virus scan, which came up empty. When I connected the drive to my MacBook, the same weird changing of the modification date happened when I opened any folder with an 8/3/18 modification date. Why is this happening?
