MacBook charger cable damage
My MacBook charger cable has had the outer plastic coating damaged in 3 places to the point where the wire was exposed. The wire itself doesn't seem to be damaged and I have wound electrical tape around the damaged areas which seems to work nicely. The battery gets charged except it is now 10 years old and in need of replacement.
Question #!: Will my repair affect the charging process and/or damage the battery. My battery has issues and needs to be replaced so I want to make sure it is ok to use the charger on the new ($500.00 YIKES!!!) battery replacement.
Question #2: There are third party chargers online. Are these safe to use and has anyone purchased one of these? If so what brand?
Thanks
MacBook Pro 15″, macOS 10.12
