iPadOS 15: Apps are finally allowed to use more RAM

Apple has made an important change for professional programming on its tablets with iPadOS 15, which will be released this Monday. As announced in the summer, the existing RAM limit for individual apps has been increased significantly. In the previous version, iPadOS 14, the limit was 5.1 GB per application, which was particularly surprising because Apple integrated up to 16 GB of main memory for the first time in the iPad Pro M1, which was released in the spring.

The models with 256 and 512 GB of storage space have 8 GB of RAM, the expensive 1 TB and 2 TB versions of the iPad Pro even have double that. Memory-hungry programs could not make full use of this RAM: Buyers of the top models, which cost well over 2000 euros, complained that they cannot use more levels in professional apps such as the Procreate painting app than on the somewhat cheaper 8 GByte RAM iPads.

Everything is getting better in iPadOS 15. As developers say, Apple allows them through a special Entitlement (“Kernel Increased Memory Limit”) to request up to 12 GByte at a time – with the iPad Pro M1 with 16 GByte RAM. In the case of the iPad Pro M1 with 8 GB of RAM, it is now 6 GB, a little more than the around 5 GB previously allowed. Entitlements must be applied for by developers directly from Apple, but approval is usually quick. The group wants to avoid that apps unnecessarily request a lot of RAM. iPadOS 15 also provides a buffer of 2 GB each.

Professionals now have the hope that graphics or computation-intensive applications will run faster on the iPad Pro M1. In addition, there is always hope that Apple could also give the devices its own professional programs Final Cut Pro X and Logic Pro’s own versions. This would allow Apple to further set the iPad Pro apart from the other iPads. iPad 9 and iPad mini 6, for example, only have 3 and 4 GB of RAM, respectively. Here Apple should proceed more conservatively when assigning the entitlements in order not to cause problems in the standard operation of the tablets. For years, Apple had not given any information about the RAM inventory of the iPads (as well as the iPhone); that changed for the first time with the iPad Pro M1.
