MacOS client 2020

uroni · December 1, 2020, 7:09pm

Thread to track macOS client status.

@Moisie correct me if I am wrong, but this is the stuff to be done till there is a (working) pkg again:

Integrate notarization into build process
Somehow setup builds. @Moisie do you need Apple developer membership?
Fat-binaries for Apples ARM64 transition
Big Sur probably broke it again, so it needs testing there

Nice to have:

Ask with explanation that the App bundle is added to Full disk access (see e.g. https://github.com/MacPaw/PermissionsKit/blob/master/PermissionsKit/Private/FullDiskAccess/MPFullDiskAccessAuthorizer.m or other backup software e.g. https://kb.acronis.com/content/62133 )
Integrate with time machine snapshots/use APFS snapshots
Low priority: Finding out how APFS sparse files work and supporting those

Current test version:

Known issues:

~~The folder /Library/Application Support/UrBackup Client/var/urbackup/data isn’t created during installation. This causes file backups/settings exchange to fail.~~
Crashes on macOS 10.13.6

Hi:

That’s pretty much right, yes. At present I’m working on (as far as I can see) the last show-stopping issue otherwise, which is to integrate the wxWidgets libraries into the application bundle, so they don’t need to be installed separately.

I have Apple developer membership through the company I work for - but I’m unclear on the best practice for signing apps on a shared, open-source project. Obviously I don’t want to risk my company’s certificate being revoked for sections of code I have no control over - but contrarily, I understand you might not want to sign code that you haven’t written!

I honestly don’t know if I’m being paranoid here - but I just don’t want to jump into a situation which might be irreversible, without fully understanding the consequences…

I don’t yet know how possible this will be: full integration appears to be reserved for select developers - and Time Machine snapshots will get cleared up by the OS after ~24 hours. This might be sufficient to effect a practical solution - at least individual files won’t be transient whilst they’re being backed up, but it won’t necessarily be possible to backup a full disk snapshot within that time period.

Other items I have on my non-show-stopper list are:

I’m not convinced that background priority is being correctly applied;
Work through macOS-specific metadata backups - as per this thread;
A few GUI tidy-ups.

I’d link it statically (*.a files). Since there is only one executable file, you wouldn’t gain anything by dynamic linking anyway.

I’d use a separate one. I was asking because I can forward you the fees from donations, if necessary, or perhaps others could help.

I currently don’t have one. As perhaps mentioned in the other thread, the Mac stopped getting updates. Then Apple required an (up-to-date) i-Device as second factor for the developer account. At this point I couldn’t even cancel the account anymore and support wouldn’t cancel the account for me. Luckily my credit card CVC changed which fixed the issue.

I would perhaps consider building it on https://www.macincloud.com/ but if that i-Device second factor requirement still exists, I’d have to buy an Apple device anyway, so it’s cheaper if you do it

Moisie · August 6, 2020, 4:27pm

Ok - I’ll look at that too - thanks!

No problem - presumably that would be best tied to an @urbackup.org email address? I’m happy to work however’s best for you on this front - just let me know what’s best for the project, and what’s easiest for you.

I can’t exactly remember the sequence of events - but I remember this happening and being annoyed by the prospect. However, someone then just pointed out to create a second user account on my Mac, sign that account into the iCloud account, and use that for the two-factor sign-in - no i-Device required.

Certainly for the foreseeable future, I’m happy to do the build process. I haven’t yet gone through a build which ties into the get-the-version-number-from-git procedure - but I’m happy to work it out (presumably this requires coming out of the dev branch?).

uroni · August 6, 2020, 5:10pm

Reading https://developer.apple.com/support/authentication/ closely, I might be able to make it work with https://www.macincloud.com/ and SMS 2FA. I guess that would be the cleanest solution (if it works). I’ll give it a try and see how good your build instructions are, k?

(With i-Device I meant this (it doesn’t work with iCloud for Windows):

What are the system requirements?

You can enable two-factor authentication on an iPhone, iPad, or iPod touch with iOS 9 and later, or a Mac with OS X El Capitan and later.

)

Moisie · August 6, 2020, 6:47pm

Ah right - that makes sense. Yes - you’d need a reasonably modern Apple device to accept their custom 2FA push notifications.

uroni · September 9, 2020, 4:25pm

Finally got that 2FA thing figured out after a lot of back and forth with support over several weeks. Result:

final-signed.pkg (5.9 MB)

It doesn’t work because /Library/Application Support/UrBackup Client/var/urbackup/data isn’t created (I think). But after that it looks good.

uroni · September 9, 2020, 7:05pm

It doesn’t properly switch into dark mode ( https://trac.wxwidgets.org/ticket/18146 ). This seems to be improved with wxWidgets 3.1.y. Any reason why you emphasize using the stable wxWidgets version in the readme?

Moisie · September 10, 2020, 5:43pm

Woop - I apologise on behalf of the Apple community, and thankyou for your persistence!

Hmmm - it does work here - I can’t think why that wouldn’t get created, just as it was previously created inside the application bundle with the old version.

Yes - it didn’t build for me at all with the later wxWidgets. Since I found 3.0.5 stable worked, I haven’t tried again - I’ll put it on my list and report back. (Sorry - haven’t had much time to spend on this recently.)

(Incidentally there’s an outstanding PR for linking the required wxWidgets into the application, so no separate installation of it is required. )

uroni · September 10, 2020, 7:29pm

Sorry, didn’t see. The above build is statically linked (which would in this case also e.g. reduce the size). I updated the readme w.r.t. that.

Could be it was another issue… I had problems with / in the mac serial id (which is added to the default client name), but that problem was fixed server side.

Moisie · September 11, 2020, 7:39am

Ah brilliant - thanks!

uroni · September 11, 2020, 4:54pm

Build it with wxWidgets 3.1.y. Seems to work: final-signed.pkg (6.0 MB) Had to move min-version up to X 10.10.

uroni · September 11, 2020, 4:56pm

The “Access/restore backups” option in the menu doesn’t work for me (open web browser).

Moisie · September 16, 2020, 5:10pm

Hi,

Sorry - rather behind on my ability to test your updates at this end. However:

This is working on the build and OS (macOS 10.12.6) I’ve been focussing on.

Moisie · September 30, 2020, 2:20pm

Hi:

Finally had chance to run your build on a macOS 10.15 system.

I found that with your built package - but it looks fine on my (earlier) build script. Presumably something amiss with line 165 of Makefile.am_client ?..

Again, with your built package on my macOS 10.15 system, that is working here.

uroni · September 30, 2020, 6:10pm

Ok, added it to known issues in OP.

One cause could be that depending on the amount of data it needs to send to the server (depending on amount of users e.g.), it uses different methods to call the web browser:

github.com

uroni/urbackup_frontend_wx/blob/dev/TrayIcon.cpp#L599


			params+="&is_file=false";
		}
		else
		{
			params+="&is_file=true";
		}
	}

	if(!params.empty())
	{
		if (params.size() > 2000)
		{
			wxFileName tmpfn(wxStandardPaths::Get().GetTempDir(), wxT("urbackupclient_fileaccess.htm"));
			wxTextFile file(tmpfn.GetFullPath());
			file.AddLine("<html><head>");
			file.AddLine("<meta http-equiv=\"refresh\" content=\"0;URL='" + params + "'\">");
			file.AddLine("<script type=\"text/javascript\">");
			file.AddLine("window.location.href='" + params + "';");
			file.AddLine("</script></head><body>");
			file.AddLine("You will be redirected to your UrBackup instance. <a href=\"" + params + "\">Click here</a> if not.");
			file.AddLine("</body></html>");

Hello,

I’m trying to set up an urbackup client on MACOS 10.14 and 10.15.
I can’t do it.
If I download the client from the web interface, it doesn’t work and if I download the versions of this post, I can’t configure it.

Could someone help me? Please help me

Moisie · October 12, 2020, 12:18pm

Hello:

Use the version linked in this post, and after installing it, run these commands in Terminal:

sudo mkdir /Library/Application\ Support/UrBackup\ Client/var/urbackup/data
sudo chown root:root /Library/Application\ Support/UrBackup\ Client/var/urbackup/data
sudo chmod 700 /Library/Application\ Support/UrBackup\ Client/var/urbackup/data

After that, you should be able to run and configure the client successfully. You will also have to give the client Full Disk Access in System Preferences > Security & Privacy > Privacy > Full Disk Access.

Please let us know how you get on!

Buzzz · October 12, 2020, 1:28pm

The installation of version 2.5.7beta is error free.

I executed these three command lines
"
sudo mkdir /Library/Application\ Support/UrBackup\ Client/var/urbackup/data
sudo chown root: /Library/Application\ Support/UrBackup\ Client/var/urbackup/data
sudo chmod 700 /Library/Application\ Support/UrBackup\ Client/var/urbackup/data
"
I changed the second one from root:root to root: OK
I gave access to the entire hard drive to Urbackup client. OK

I can’t set up the client. I have only 4 choices from the URBACKUP client icon.
Access Backups, about, status, uninstall.

sudo urbackupclientctl status
Password:
/usr/local/bin/urbackupclientctl: /usr/local/bin/urbackupclientctl: cannot execute binary file

sudo ./urbackupclientbackend
Segmentation fault: 11

Version MacOS 10.13.6 High Sierra

How do I configure it?

Moisie · October 12, 2020, 3:14pm

Hello:

First try a reboot; if that doesn’t help, then see if there is anything useful in the log file:
/Library/Logs/urbackup_client_backend.log

Thanks.
