Inspect signed entitlements and permissions, load commands, memory layout, dependencies, symbols and runtime evidence for each slice.

Select a Mach O file

Choose a binary and architecture. Detailed tables load on demand, not with the initial page.

Integer fields use hexadecimal, without locale separators or loss of 64 bit precision. JSON downloads preserve the original numeric data. Tables retain up to 10000 records each, with totals and truncation markers. Signing data is descriptive; trust and code page hashes are not verified. Not disassembly.

Under the hood

Frameworks & engines

Embedded code and runtime evidence from this build, not other releases.

0 embedded libraries

No engine identification recorded for this build. That does not mean the app has no game engine or runtime.

No embedded framework records

Statically linked libraries cannot be identified from file paths alone.

Recorded signals

Package details

Only the analyzed build

Privacy & permissions

Not recorded

No parsed privacy manifest or Info.plist signals available for this build. This is not a statement about tracking behavior.

Static observations

0 recorded

No observations recorded for this build. Missing findings are not a security assessment.

Analysis record
Method
Stored static package extraction and inventory; not a live security test.
Coverage
Only the selected build is represented. Missing data means not analyzed, not safe. Scanner identity and scan time are unavailable for sources that did not record them.
