Dopamine 3 Compatibility: Supported iOS Versions by Device Category

Key points

• Dopamine 3 is described in its 3.x README as rootless and semi-untethered.
• arm64e is documented from iOS 15.0 through iOS 17.3.1.
• A12 and A13 are documented from iOS 15.0 through iOS 18.7.1, plus a separate iOS 26.0 through iOS 26.0.1 range.
• arm64 is documented from iOS 15.0 through iOS 18.7.1.
• The two A12/A13 ranges must not be combined into one continuous iOS 15.0 through iOS 26.0.1 range.
• The 3.x README is the relevant source for current version ranges when older compatibility text differs.

Dopamine 3 compatibility at a glance

The documented compatibility information is divided into arm64e, A12/A13, and arm64 lines. The applicable device category must be considered together with the installed iOS version.

The 3.x README lists arm64e from iOS 15.0 through iOS 17.3.1; A12 and A13 from iOS 15.0 through iOS 18.7.1, plus a separate range from iOS 26.0 through iOS 26.0.1; and arm64 from iOS 15.0 through iOS 18.7.1.

• arm64e: iOS 15.0–17.3.1
• A12 and A13: iOS 15.0–18.7.1, plus iOS 26.0–26.0.1 as a separate range
• arm64: iOS 15.0–18.7.1

arm64e: iOS 15.0 through iOS 17.3.1

For arm64e, the documented range begins at iOS 15.0 and ends at iOS 17.3.1. The endpoint should be retained whenever the range is summarized.

The shorthand iOS 17 must not be interpreted as support for point releases beyond iOS 17.3.1. Compatibility outside the cited arm64e range is not established by these facts.

• Documented start: iOS 15.0
• Documented endpoint: iOS 17.3.1
• The architecture condition applies throughout this range

A12 and A13: two separate documented ranges

A12 and A13 have one documented range from iOS 15.0 through iOS 18.7.1 and an additional, separate range from iOS 26.0 through iOS 26.0.1.

These ranges must not be merged. The supplied information does not establish support for versions after iOS 18.7.1 and before iOS 26.0. A precise summary is: A12 and A13 support iOS 15.0–18.7.1, plus iOS 26.0–26.0.1.

• First range: iOS 15.0–18.7.1
• Additional range: iOS 26.0–26.0.1
• The iOS 26 range applies to A12 and A13
• The source does not establish one continuous iOS 15.0–26.0.1 range

arm64: iOS 15.0 through iOS 18.7.1

The 3.x README lists arm64 from iOS 15.0 through iOS 18.7.1. The supplied facts do not add the separate iOS 26.0–26.0.1 range to arm64.

Within the documented continuous range, iOS 16.0, iOS 17.0, and iOS 18.0 are included. This arm64 line remains distinct from both arm64e and A12/A13.

• Documented start: iOS 15.0
• Documented endpoint: iOS 18.7.1
• The separate A12/A13 iOS 26 range does not apply to the listed arm64 line

How to interpret iOS shorthand

Broad labels such as iOS 15, iOS 16, and iOS 17 should always be read with the relevant architecture or chip-family condition. A major-version label does not replace the documented endpoint.

The label iOS 18 applies only to categories whose documented range reaches iOS 18.7.1: A12/A13 and arm64. It does not establish universal iOS 18 compatibility, because arm64e has a separate endpoint at iOS 17.3.1.

The label iOS 26 is narrower. The supplied facts document iOS 26.0 through iOS 26.0.1 for A12 and A13 only.

• Pair every iOS version with arm64e, A12/A13, or arm64.
• Do not extend iOS 17 arm64e support beyond iOS 17.3.1.
• Do not treat iOS 18 as universal across device categories.
• Do not extend the A12/A13 iOS 26 range beyond iOS 26.0.1.

Rootless and semi-untethered design

The Dopamine 3.x README describes Dopamine as rootless and semi-untethered. The official website explains that rootless software limits writes to certain parts of the filesystem.

The same information notes that tweaks may need to be updated or recompiled for rootless support. This environment detail is separate from the iOS compatibility ranges: a listed operating-system range does not by itself describe compatibility for every tweak.

The official website identifies Sileo and Zebra as package managers associated with Dopamine.

• Dopamine is described as rootless and semi-untethered.
• Rootless operation limits writes to certain filesystem areas.
• Tweaks may need rootless updates or recompilation.
• Sileo and Zebra are identified as associated package managers.

Which source contains the current ranges?

Use the official Dopamine 3.x README facts for the current compatibility ranges. The official website's displayed compatibility text may lag the newer 3.x README, so older displayed ranges should not override the 3.x information.

For an accurate comparison, identify the device category first and then compare the exact iOS version with the applicable documented range. This hub focuses on compatibility rather than reproducing narrower guides or setup instructions.

• Prioritize the 3.x README for current version ranges.
• Keep the architecture or chip-family condition visible.
• Compare the exact iOS version with the relevant endpoint.
• Do not infer support for categories or versions absent from the listed ranges.
