“Technology can be our best friend, and technology can also be the biggest party pooper of our lives.

Disable Mac OS X Gatekeeper

Ocassionally, there is a need to install an app created by a developer that is not identified by the security policy in place on the Firm’s MacBook.

Here is the short procedure I identified it works for me:

  1. in terminal type: sudo spctl --master-disable
  2. verify with: spctl --status
  3. open the application and quit it
  4. in terminal, type: sudo spctl --master-enable
  5. verify the status: spctl --status
  6. verify that the policy is restored via: System Prefrerences … -> Security and Privacy  -> General

Using @SQLcl (to be updated)

Taking the new command line tool @SQLcl for a first test drive.

Plus Points
– installation super-easy
– a lot of commands interchangeable with SQL Developer
– connectivity via TNS is easy to setup. TIP: if you do not have TNS_ADMIN environment variable in place, run

show tns

in SQL Developer in order to get the location for the tnsnames.ora file!

Minus Points
No minus points found yet 🙂

Conclusion
Nice tool
