Illustrator: cannot undo sometime

Adobe, Illustrator

When I was editing an illustrator file, I got quite a scare when all of sudden “undo” doesn’t work anymore. Not just the cmd+z doesn’t work, the whole “undo” function is ineffective. After taking some deep breath, when I was able to think again, I noticed that “undo” was only ineffective after I changed certain objects, in this case, a symbol. Changes of other elements were fine. I noticed a little framed “+” icon at the right bottom corner of the symbol thumbnail, now I learn that it is an icon to indicate that it is a “dynamic symbol”. Something like this:


Changing the symbol to “Static Symbol” fixed all the problems!!

Now I learned that “What you can’t do is move, delete, or even scale those individual elements.”

I hope it helps you if you encountered something similar.

Getting rid of stubborn files in TWO steps:

Step 1: Launch Terminal

Type “Terminal” in Spotlight, if you’d never used Terminal

Step 2: Type commands in Terminal:

Then remove the file “file_that_I_cannot_kill.dmg”

Illustrator: Create a new document based on a customised profile


You can create a new document in Illustrator, you can choose the profile of that new document. In the newly created file, all symbols, swatches and Artboards will be the same as the template.


If you save an *.ai, or *.ait (illustrator template) file in the right place, you will see this template in this list as well.

Here is the place:

Users > $your_user_name# > Library > Application Support > Adobe > Adobe Illustrator $version number# > $language# > New Document Profiles


Now, give it a try!!

Disable Google Chrome Notifications


I’m using Google Chrome 41.0.xxxx.x on Mac OS 10.10.1. Apparently since version 35.0.1916.114, there is this “Chrome Notifications” icon in the system tray. I somehow just noticed today.

It looks like this: notifications

You cannot really choose not to see this notification in the system tray from the settings of the notification itself:


If you don’t want to hide the notification icon in the system tray, you need to go to Chrome -> Hide Notifications Icon
