Frequently Asked Questions

1. Will macOS Big Sur 11.5.1 slow down my Mac?

Well, it entirely depends on the system storage left on the machine for you to work on. It might slow down with the biggest difference you can make. However, there are no such proven results that BigSur slows down during macOS. Also, with the new updates coming in, you can see better effects.

2. Can I install the new update on my old Mac?

It depends on how old your MacBook is. As for now, the new BigSur 11.5.1 updates are for every mac running on the BigSur 11.5 or lower. However, by old you mean older than the 2014 MacBook, it might not work for you. These are pretty heavy security updates and might be suitably available for a MacBook that old.

3. Why won’t my Mac download the new update?

If your Mac is unable to give you the latest updated information on the system, it is because you do not have enough space to do so. 

For this, you need to either empty your trash or delete some items from your Macintosh HD Drive. There might be applications that are unattended for a very long time and you can simply get rid of them. Furthermore, once you are done, restart the system, and try the update process again.

Final Verdict

Here is everything you need to know about the macOS BigSur 11.5.1 update and all changes you might see. Days before this, Apple had introduced the new BigSur 11.5 update and a multitude of changes brought with it. However, a lot of users had been using the older version still and this might be the best opportunity for anyone to take the leap and directly head over to the new security update with all the features for the 11.5 update too.
