My flawless cross-platform data sync experiences

In this article, I would like to share my own experience of how I use different service providers to make sure that my files, music, passwords, emails are available on all my devices. Be it macOS, Windows, Android or iOS. The services detailed below reflect my personal preferences. It is possible that there are better providers that are cheaper or that offer more functionality. If you know of such, help readers by writing in to tell us what works for you. I personally do not like Google’s services. I will not recommend Google Drive, Authenticator and other services in this article, but I am sure that their solutions can solve the architecture I consider to be proven.

What I’d like to show you is how I manage in my daily life to make sure that all my data is in sync and accessible on all my devices, almost without exception.

File Storage and e-mail account. Notes, Calendar, Contacts.

I personally chose Microsoft’s OneDrive technology as my storage and email provider. They give you 5GB of cloud storage space in their free plan, and an extra 15 GB for emails. For a very long time I subscribed to Microsoft OneDrive +100GB for $2 per month, which is fair, but then recently I decided to subscribe to Microsoft Office 365. Partly so I could have a licensed Microsoft Office subscription of my own to access important files on my personal computer, and partly because they are increasing the cloud storage to 1TB. On top of that, we also get support for recovering our deleted, lost files, or if a file encryption caused by a ransomware virus happens, it can detect and stop the operation. The one terabyte package runs around $60 for a year (+VAT, which is 27% in Hungary). If you buy it, you’ll also no longer have to watch the notifications on the web interface. You also get the desktop versions of these in addition to the web versions of Excel, Word, Powerpoint. You can install the desktop version of Microsoft Office on 5 computers with one license key.

OneDrive use pretty serious file encryption, so you can feel safe with your files here, but if you have something really personal in your cloud, there’s the safe feature, which uses an extra encryption algorithm in addition to a number of security requirements

On Windows the OneDrive client is integrated, on macOS it can be installed separately, it integrates quite nicely into the system. You can configure them not to download the entire cloud content to your computer unnecessarily, but to have a file available in the file structure in case you want to store it. What it does is download the file to the physical hard disk before use. This saves a lot of space.
On Android, the OneDrive client also integrates quite well with the operating system, but I don’t use an Android device on a daily basis, just an iPhone.
Mobile clients can automatically back up your camera roll. The upload is an interesting solution for iOS, as they couldn’t do it in the background: they developed a screen called “Night Backup”, which basically layers a wakelock on the display and takes the brightness off the phone. You can view files on your mobile “without downloading”. Handles the web client for the iPhone HEIC format.

Your Outlook email address can be accessed via an Exchange server, which also allows you to save Calendar and Reminders, Notes, Contacts. Personally, I have all syncing turned off in iCloud because I sync my notes to my Outlook account. If you set macOS and iOS to take your outlook email address as your Internet account, the built-in Notes, Email, Calendar app can handle it. This is good because in Windows it’s also built-in to sync everything to the outlook account, so you get a Notepad and Calendar on top of the emails. So if you add a meeting to your calendar, it’ll show up immediately on your iOS/Android device, and also on macOS. Of course it works in all directions. The only downside to the notepad is that on macOS you can’t bold letters, insert a diagram, etc. in the notes app. So if you have an iPad and an Apple Penciled, you’ll have to choose a different way to draw.

Plus one thing besides Outlook that I haven’t seen with any other provider: you can assign aliases to your email address. So you don’t have to register a new email address if you get bored of your old email, you can simply add another address to the account and use up to 10 email addresses with one mailbox.

This is probably the subject I have dealt with the least. I spend about 80,000 minutes a year listening to music. I clearly chose an online music service provider. My choice was Spotify. Since then, I have tried a service called Tidal once, which is quasi the same as Spotify, but lossless music, but I didn’t feel it was worth the extra money, I couldn’t take advantage of it.
Spotify has the ability to sync playlists between all platforms. It has a relatively good algorithm for recommending music. You can download tracks of reasonable quality for offline listening on its mobile app. The radio in my car supports it natively. Of course, the 1TB of storage space could hold a lot of music, but you don’t have to worry about downloading it

Password management and two-factor authentication

I never use the same password on any service. In fact, it could be said that I don’t even use passwords, because I don’t know any of them by memory. This is because I let the computer generate super long and complicated passwords. That’s pretty much how to use a password manager effectively, and how to perhaps exist one step more securely on the Internet.

What was important to me was to make the password manager work on macOS and windows, and to be able to add passwords to iOS not only in safari, but also in the apps.

Microsoft Authenticator could have been the perfect solution, but it wasn’t. ( As I am logged in to my work account on my devices, where the password storage functionality of the Authenticator application is disabled by policy, I cannot add passwords to my personal account. But maybe that’s okay, it’s less responsibility on my Microsoft account. After much searching, I found LastPass to be the most sensible password management application. It works on mac on windows, in all browsers, and integrates with iOS. And it can also fill in passwords in apps.

Another very important thing is to protect your account from unauthorised access. Almost all websites can be set up with two-factor authentication, be it Instagram, Facebook, GitHub, etc. Lastpass also has an Authenticator application that can generate such two-factor passcodes. Just like Microsoft authenticator. I’ve set up two-factor authentication everywhere.

Run .NET MAUI apps with Visual Studio for Mac

VS for Mac 17.0 Preview version is not yet supporting MAUI applications. But you can run them on macOS too, but you will need a terminal window for it!

MAUI projects can not be set as a runnable project (yet)
.NET 6 Xamarin and MAUl projects are not supported with this version of Visual Studio. The included target frameworks are not supported: net6.0-android|net6.0-ios|net6.0-maccatalyst

If you are not familiar, how to set up your environment to start developing with .NET newest technology named MAUI, then read this article by me:

Build and run on macOS

Open up a terminal, and navigate next to your .sln file. Give out the following command:

dotnet build YourSolutionName -t:Run -f net6.0-maccatalyst

This will run your application on macOS. If you wish, you can change the last parameter to net6.0-android or net6.0-ios too.

SourceTree keeps asking for password on macOS

If you are experiencing that the sourcetree is keeps asking for username and/or password when fetching, pushing, pulling, commiting to a repository, open up a terminal and execute the following command

git config --global credential.helper osxkeychain

This happened for me after installing a third party password manager, called LastPass.

Setup .NET MAUI project on macOS

You may also be interested to know how Xamarin.Forms has grown and who will be its successor. I was interested too, so I took the time between the two holidays to test the .NET MAUI developed by Microsoft, so you’ll get a couple of articles about it. First, I’ll show you the installation and how I managed it under macOS.

It’s possible that by the time you read this post, you’ll be able to create a MAUI project from UI, but it’s not currently an available feature for me. However, a lot of the tutorials were outdated because .NET 6 with VisualStudio2022 has been released, and xCode 13 is not in beta either, so you can skip some unnecessary installations.

But what is definitely needed

  • macOS capable device,
  • Visual Studio 2022,
  • xCode 13.

Get started on macOS

First thing first, fire up your macOS terminal, because we will start working in that.

If you havent installed Redth’s MAUI check tool yet, lets do this with the command

dotnet tool install -g

Once it has been successfully installed, you will see the following output

You can invoke the tool using the following command: maui-check
Tool '' (version '0.10.0') was successfully installed.

So it says, that you can invoke the maui-check command from now on, but it’s a lie, since some things of ZSH terminal, we need to manually fresh up the terminals internal things, otherwise the maui-check command will fail with “Unknown command”.

export PATH=$HOME/.dotnet/tools:$PATH

From now on, you can freely invoke the


Which results you the following output:

      _   _   _____   _____     __  __      _      _   _   ___                  
     | \ | | | ____| |_   _|   |  \/  |    / \    | | | | |_ _|                 
     |  \| | |  _|     | |     | |\/| |   / _ \   | | | |  | |                  
  _  | |\  | | |___    | |     | |  | |  / ___ \  | |_| |  | |                  
 (_) |_| \_| |_____|   |_|     |_|  |_| /_/   \_\  \___/  |___|                 
? .NET MAUI Check v0.10.0.0 ?
This tool will attempt to evaluate your .NET MAUI development environment.
If problems are detected, this tool may offer the option to try and fix them for
you, or suggest a way to fix them yourself.

Thanks for choosing .NET MAUI!
⏳ Synchronizing configuration... ok
⏳ Scheduling appointments... ok

It can fix a lot of things for you automatically, watch the output carefully, it prompts that you want to fix the issues or not.

To be honest, i don’t know this command will do the work any of the things above, but if you run this, after doing the things above, its also fine:

sudo dotnet workload install maui

Create a new MAUI project

Lets find a suitable place for our new project, then give out the following command:

dotnet new maui -n YourMauiProjectName

From now on, you can leave the terminal, and start editing the project in your favourite IDE, example the VS2022

Run your very first application

Since the projects are cannot be set as run projects in Visual Studio 2022 yet, we need to run our apps from the command line with this command

dotnet build YourMauiProjectName -t:Run -f net6.0-maccatalyst

This will run your app with mac Catalyst compilation, but you can create Android and iOS versions also with this command
