Apple today updated its vintage products list to add the 2018 Mac mini and the iPhone 6s, devices that will get more limited service and repairs now that they are considered vintage. The iPhone 6s initially launched in 2015, but Apple kept it around as a low-cost device until 2018, which is why it is only now being added to the vintage list.

All day to learn 5, yes count 'em, two letter words ?

Here you go :

ls - list files
cd - change directory
cp - copy
mv - move
rm - delete

All done in 2 minutes.
In your bid to sound better than the other poster, you are giving dangerous advice. I use the terminal often, but using those commands is difficult without knowing how they work and potentially dangerous.

Performance improvements:

1. Previously, when one used to open the app, the app would open as a picture with a processing image and then come to action in 2-3 seconds or maybe more. This is removed in this update as I see it. When you start an app or do anything, it first recovers all the require data and then opens the app completely. A great user experience improvement in my opinion.

2. For most people, Safari was unusable before. Safari is fine now. Although there are some gripes, overall it feels good and is very usable. Safari Version - 5.1 (7534.34.4)

3. The overall usage is just awesome. I cannot explain how the OS has been awful on low specced machines. But as expected, it was supposed to get better and now with DP3, its become exceptionally well. It just works great.
Very smooth on MacBook Late 2008 [standard without upgrade].

4. LaunchPad is now closer to perfectness. There are no issues with making folders. The animation is gone but it feels very smooth. No problems at all. There's an extra Utilities folder which is empty. But it doesn't bother me as I don't use LaunchPad. :cool:

5. Launching Mission Control has become smoother but still requires a lot of work. A lot.

6. As explained in Pt.1, launching of apps can take some time as it caches the app+data/document completely.

7. The login is pretty smooth and going from the login screen to the home screen is awesome. It's plain but it makes a lot of sense. Might witness a delay but its worth the wait. :cool:

Ugh why does every thread have to become a nerd pissing contest? What does any of this squabbling do other than to cause strife and derail threads?


Now go ahead, flame away.
