Bitcoin Core not syncing completely at start up

Ever since I open Core on Feb. 4th it hasn’t continued to sync any more. It worked when originally downloaded but now the progress has stopped, leaving me at 98.43% and claimed the “Estimated time left until synced” Unknown. I’ve tried to delete and redownload multiple times. It seems impossible to fully delete the existing GBs on my MacHD. Any suggestions would be greatly appreciated!
