apple silicon M2 使用 intel 版本软件时如何禁用内存的写入保护

papers3 在导入 pdf 时发生闪退, 分析原因是软件无法写入导致的.
由于本人不懂代码, 勉强查到了一些可能的原因:
由于 apple silicon 的 Write Protections 导致

Porting Just-In-Time Compilers to Apple Silicon
https://developer.apple.com/documentation/apple-silicon/porting-just-in-time-compilers-to-apple-silicon
附上崩溃报告, 还请专业人士指点如何才能让这个软件具有写入磁盘的能力, 谢谢!
(SIP 关闭与否都会崩溃)

你发的这两个链接是关于 JIT 编译器需要注意的 Apple Silicon 内存写保护特性，感觉和你这个软件以及这个错误没什么关系。错误报告里看起来是在试图访问空指针
