Reason not to install the new Apple computer software update yet...
- Greater risks than rewards
The newest version of Mac-OS has just been released but its not advisable to install yet at least not now.
The software is great and very interesting exactly what one should expect from Apple's Engineers, but experts advice its still a bit too risky now, advisable you wait till everything is well in order or for more confirmation you could go to the Mac-OS official community. Preferably make sure you have all your important data backed up on an external drive before installation, just like you would before installing any other OS for security reasons in case anything goes wrong during the process. Just make sure to confirm the reliability from Apple. Like I said earlier there are 'greater risks than rewards' for now, so its wise to be patient.
