2015 MBP: Is it possible to upgrade from Sierra to Mojave and KEEP HFS+?

I have heard it is possible with high sierra, but I am having trouble finding anything about keeping HFS+ on Mojave that is not reliant on using an external hard drive. But, I haven't seen anything new in the last few months?

MacBook Pro 15", macOS 10.12

No. Mojave demands apfs.
What is the issue?

The sort of issue which can arise is illustrated by my own position. My iMac (which I think might accept Mojave) and my laptio (which won't) communicate using file sharing to keep documents etc. in sync. If upgrade the iMac to Mojave the laptop will no longer be able to see it in File Sharing - the other way around would work but my experiences it that though you can 'pull' files using File sharing you cannot 'push' them. So this free upgrade would cost me whatever a present-day laptop costs.

HFS+ is important for compatibility and network reasons for me.

File systems local to any computer is meaningless in networking.

The protocols such as SMB, AFP, NFS, etc. which determine how

data is transferred between systems literally "hides" the underlying

file system of the devices and send only the data. When a device receives

the data via these protocols, it is the transport system that then

translates into the local machines filesystem format.


As for compatibility, I am not sure what your concern is when

APFS will only be on the MBP, which will benefit greatly because

it is designed for SSDs such as in your MacBook Pro.
