I want to buy a new laptop. But not exactly, if Apple, Windows, which model etc.
On the one hand I will need him for my studies to write documents and on the other hand to produce music on Ableton Live.
Have worked a lot with Apple and Windows.
Since I'm currently working full-time, I'm also willing to invest something (about 500 - 2000 Euro)
Apple may be the better choice. It's intuitive to use, it's good for music production and has excellent support for Word and Excel.
Well then look for you on notebookbilliger.de.
Should at least one
i5 CPU have 7th generation
Have 8GB of RAM
ideally also a 256GB SSD + 1TB HDD
and a clever graphics card if necessary
More attractively priced are Windows laptops. If you want to use the laptop in the university for copying, etc., I would grab a Surfacebook 2. Apple is quite good, but very expensive (the Surface is not cheap). Ableton Live seems to be running on Windows 10.
For 1800 euro https://geizhals.de/...13356.html
For 2400 euro https://geizhals.de/...13354.html
Alternatively, but raussuchen cheaper products, the Surfaces are good but also expensive.
e.g. Search with these filters: https://geizhals.de/...roductlist
As a workstation, I can only ever advise Apple products. They also fit very well into your price budget. However, they are nothing to play games.
Each OS is intuitive to use, depending on previous experience with GUIs.
'It's good for music production' is not a real statement, in this case Ableton Live does not play a role in the performance of the OS.
Office is an MS product, it works well on MacOS, but has Only a very rudimentary implementation of VBA, many scripts can only run Windows.
Nothing against Apple and or MacOS but none of what you call would be even close to a reason to MacOS…
General…
16 GB Ram are up to date. (Write down a 13-year-old 17-inch Hp Elitebook with 4 Gb. It's also wonderful.) It's still packed with study and music.
Also important is a retina display. Best picture quality. But also costs.
As memory it should be a 512er to 1TB SSD.
The CPU is a matter of faith. (My 10 year Q6600 quad core CPUs still keep up with modern CPUs.
I think with 800 euro you are there. Apple is of course more expensive. Not better.
