Adobe CS4 without activation for MacOS

1) Make sure you’ve run a CS4 app once (use trial if asked). Quit any open CS4 apps.

2) If you’ve previously entered a serial,
load any CS4 app, go to the Help menu and Deactivate. Quit any open CS4 apps.

3) Open Terminal (found in Applications/Utilities/)
sudo /Applications/TextEdit.app/Contents/MacOS/TextEdit /etc/hosts

4) Enter admin password.

5) A file will automatically open in TextEdit.
In TextEdit, add new line at the bottom of the document and paste in the following:

127.0.0.1 activate.adobe.com
127.0.0.1 practivate.adobe.com
127.0.0.1 ereg.adobe.com
127.0.0.1 activate.wip3.adobe.com
127.0.0.1 wip3.adobe.com
127.0.0.1 3dns-3.adobe.com
127.0.0.1 3dns-2.adobe.com
127.0.0.1 adobe-dns.adobe.com
127.0.0.1 adobe-dns-2.adobe.com
127.0.0.1 adobe-dns-3.adobe.com
127.0.0.1 ereg.wip3.adobe.com
127.0.0.1 activate-sea.adobe.com
127.0.0.1 wwis-dubc1-vip60.adobe.com
127.0.0.1 activate-sjc0.adobe.com

6) Run any CS4 apps. And put these serial numbers

1325-0148-7083-3854-2685-9910
1325-0531-4465-2036-6115-2889
1325-0160-0444-0107-1848-9998
1325-0078-9095-1778-2946-7438
1325-0958-7730-6187-6642-9656
1325-0359-2403-9028-3122-1443
1325-0484-5484-8715-0325-1405
1325-0803-8403-1768-8621-9444

7) Confirm CS4 is running properly

8) But after few days, there will be
"serial is not available, make new serial blah blah"
Before that, first we have to protect 'cache.db' file

9) Open 'Terminal' and
cd /Library/Application Support/Adobe/Adobe PCD/cache/

10) cp cache.db cache.db.bak (for backup)

11) sudo chmod 000 cache.db (protection for cache.db)

12) enter password
