Macbook Pro Updating macOS issues
I'm having problems updating my OS to 10.15.3. Every time I click 'Update Now', it suggests to restart my laptop, which i do, but it continues the process of suggesting to restart. I deleted files and made plenty of storage space for the install. No joy. I tried to install the previous OS (10.15.2), but the install fails to go through. I've restarted my MacBook so many times and tried to install this update, I'm stuck on ideas. Please help! Thank you for your time.
MacBook Pro 13", OS X 10.11
