Hi friends,

Well, isn't this funny? When I try to copy files from my iMac (running Mojave) to me MacBook Pro (running High Sierra) sometimes it works and sometimes it doesn't.

Isn't that strange?

Any ideas?

Thank you.
 
Do you get some kind of error message when the copy fails?

Are you copying large numbers of small files - or small numbers of large files - or just one or two files, which might be any size?

Do you always use the same process to copy files?
 
No, no error message.

Re: Large - small files. It varies.

Yes, it is always the same process.

I just copy from the iMac and paste to the MacBook Pro, same as I've always done.

It never happened when both machines were running Sierra, or any other macOS.

Weird.

one doesn't 'copy & paste' files between macs (just text, webaddresses, etc). so... do you mean airdrop? or do you mean large & small text entries? we can better help if you better explain what you're doing.

if you're using airdrop, try turning bluetooth off, then back on. and, try rebooting your macs...
 
Of course you can copy and paste files / folders / whatever between macs.

Sheesh.

I suspect it has something to do with Mojave, as it started after I updated the iMac with it a few days ago. Previous to that both machines were Sierra. I copy a lot of image files over daily so it is a pain in the neck and one of those crazy issues that are hard to isolate. (And, I sure miss the ability to scroll through folders with Cover Flow - eliminating it with Mojave was a bone-headed move if you ask me.)

Thanks for the ideas guys.

have you tried doing this with airdrop? really easy, and (here anyway), really fast...
 
How are the two Macs connected to each other?
Network?
Wireless, or Ethernet? or not networked, but connected directly, either Ethernet, or wifi connection (no router, just talking to the other Mac.)
Or, as fisherking suggested - are you using airdrop to move the files?

Finally - when do you know that a copy has failed, if you don't get an error message of some kind? Does the copy simply stop progress, and it only copies for a few seconds then stops, or the copy never starts (and shows no progress of any kind)
 
Delta,

They are connected, in a network, using SMB and AFP, via WiFi - as they always have been for years.

The reason I knew it was happening is because I'd be moving a folder of say a gig, and it was transferring awfully fast, so I looked, and - lo and behold - not everything was there. There is no error message.

As I said, it has to be related to Mojave, as no other changes were made to the network. That eliminates everything but Mojave, as far as I can ascertain.

Airdrop works fine except I find it cumbersome because I need to see the folders / files. As part of work, I do this all day every day.
